The blocks T1 and T2 are actually matched paired dual transistors in one package, but you may go for discrete transistors, just make sure their hFes are properly matched.

A differential configuration is probably the perfect way of integrating two signals, for example here the input and the feedback signals are mixed so efficiently. Immediately after the coupling capacitor C1, the network comprising of R2, R3 and C2 forms an effective low pass filter and helps maintaining a bandwidth to a level suitable for the amplifier. Another small network at the input, involving a 1M preset and a couple of 2M2 resistors helps adjusting the off-set voltage so that the DC component at the output of the amplifier stays at zero potential.

After the differential stage an intermediate driver stage is introduced comprising T5 and T7. The configuration consisting of T6, R9 and R17 forms a kind of variable voltage regulator, which is used to set the quiescent current consumption of the circuit. The boosted signal from the above stage goes to the driver stage consisting of T8 and T9 which are effectively used to drive the output power stage involving the HEXFETs T10 and T11 where the signals ultimately undergoes a massive current and voltage amplification.

This configuration allows efficient amplification of both current and voltage at this stage. The limitation ensures low distortion at the output. Unlike bipolar transistors, here the outputs stage incorporating HEXFETs have a distinct advantage over its age old counter part.

HEXFETs being positive temperature coefficient devices are equipped with the inherent property of limiting their drain source as the case temperature tend to get too hot, safeguarding the device from thermal runaway situations and getting burnt off. Resistor R26 and the series capacitor compensate the rising impedance of the loudspeaker at higher frequencies.

Okay, thanks.The 3CXF7 power grid triode with its watt plate dissipation loafs along at legal limit Amplitude Modulation, plus It only needs one D.

The rugged 3CXF7 has a grid dissipation of watts vs the popular which only dissipates 25 watts. The 3CXA7 requires a tube socket whereas the F7 is bolted to the chassis. The cabinet, PI-L tank and right angle drives were leftovers from a partially constructed Gates transmitter.

With the major mechanical parts in place, the 80, 40 and 20 meter design was easy to build. In I added the meter band, which is described near the end of this webpage. Schematics are also included. Installed the 3CXF7 by setting it's grid ring on the top of the homebrew template and holding the grid ring down with two heavy homebrew aluminum half-circle mounting strips. I had an Eimac SK tube chimney for a physically larger 4CX so I made up the space difference by inserting a ring of teflon between the tube and the chimney and "glued" it in with GE Silicon Kitchen and Bath caulk.

Added a homebrew plate choke, glitch resistor and homebrew parasitic choke plate circuit schematic at bottom of this webpage with wire size and turns count. Installed the 3CXF7 filament transformer, two 30 amp filament chokes in parallel, the RF drive coupling caps and installed eleven 6 amp diodes between the center tap of the filament transformer and ground to set the bias at The original pf coupling caps were replaced by pf yellow ones for a little better match to the cathode as noted by less reflected power.

Since there is still some reflected power with the pf capacitors it suggests that an even greater value would be better. Internet research revealed that the bias diodes were unnecessary and were removed. For meters the two filament chokes were replaced with a higher inductance choke. Built a full wave bridge, capacitive input, Peter Dahl transformer based Volt power supply into a standard 3 foot Bud cabinet Schematic at bottom of webpage.

The high voltage fuse between the two standoff insulators was made from a single four inch piece of 30 magnet wire. If there is a high voltage short in the 3CXF7 compartment, the fuse material explodes and disappears this feature was tested.

High voltage wire between the power supply cabinet and the amplifier has a 30KV rating and is encapsulated in shielding stripped from LMR coax cable, which is grounded at both the amp cabinet and the power supply cabinet.

The power supply has a rating of Volts at 1. Click HERE to see my other high voltage supply. Outside view of both the 3CXf7 linear, the power supply and the remote viewing wattmeter. The top section of the 3CXF7 amp cabinet has a switchable inductor and a vacuum variable for tuning out the 2nd harmonic; however, the 2nd harmonic is so far down that I keep it in the switched-out position.An Amplifier circuit can be described as, a circuit which is used to increase the input signal.

But, not every amplifier circuit is the same due to their type of circuit configuration as well as operation. In electronic circuitsa small signal amplifier can be used because it amplifies a small input signal. There are different types of amplifier circuits like operational amplifiers, power amplifiers, and small signal to large signal amplifiers.

The amplifiers classification can be done based on the signal size, configuration and process of the input signal which means the relationship among the flow of current within the load as well as an input signal.

This article discusses an overview of DC amplifiers. A DC amplifier direct coupled amplifier can be defined as is a kind of amplifier where the one stage output of the amplifier can be connected to the next stage input for allowing the signals without frequency.

So this is named as the direct current which passes from input to output. The DC amplifier is another type of coupling amplifier and this amplifier is particularly used for amplifying low-frequencies like thermocouple current otherwise photoelectric current.

DC Amplifier : Circuit Diagram, and Applications

This type of amplifier can be used for both DC direct current signals as well as AC alternating current signals. The direct current amplification can be achievable only by using this amplifier, therefore later it turns into the basic building block of the differential as well as operational amplifier.

In addition, monolithic IC integrated circuit technology does not permit the production of large coupling capacitors. The circuit can be built with two transistors namely Q1, and Q2. The DC amplifier circuit can be operated without using capacitors, transformer, inductor, etc which is known as frequency sensitive components. This amplifier amplifies the AC signal by low frequency.

Whenever we applied a positive half cycle at the input of the primary transistor Q1. This transistor is already biased with the help of the divider bias network. This negative signed amplified signal is given to the base terminal of the second transistor Q2. Here this transistor is also self-biased. There are different types of amplifiers available, where all these amplifiers have a common cut-off frequency of an upper as well as a lower.

A DC amplifier has a direct current frequency like the lower limit. The higher limit is generally defined when the location of the frequency is under the middle point then the frequency will be -3dB. Whenever the frequency range is above the middle point then the output will continue to reduce the amplitude.

From the above statement, we can conclude that the amplifier was intended for flat frequency response. The characteristics of these amplifiers include the following. Thus, this is all about the DC amplifier. Here is a question for you, what is the working of DC amplifier? What is a DC Amplifier? Share This Post: Facebook.
