UHF Power Module IW2792
... The power supply is +5V with max current of 1.3A, for the bias it is necessary to adjust the right voltage which is -3.5V with about 150mA of current. To operate in SSB, AM or pulse it is suggested to increase a little the current to reach about 250mA and -3.2V in order to improve the linearity, the ...

angle modulation
... Wideband FM gives significant improvement in the SNR at the output of the RX which proportional to the square of modulation index. Angle modulation is resistant to propagation-induced selective fading since amplitude variations are unimportant and are removed at the receiver using a limiting circuit ...

DN132 - Fast Current Feedback Amplifiers Tame Low Impedance Loads
... Transformer coupling is frequently used to step up transmission line signals. Voltage signals amplified in this way are not constrained by local supply voltages, so the amplifier’s rated current rather than its voltage swing usually limits the power delivered to the load. Amplifiers with high output ...
