What is a linear RF amplifier?
Most of the RF amplifiers advertised, and most of the questions about amplifiers, are "linear" amplifiers.
What is a linear amplifier, and what other common amplifier type(s) exist that requires people to say "linear" every time they talk about RF…

What is the purpose of the transformer at the input (and output) of this RF push-pull amplifier
Firstly, feel free to move this to Electronics SE if it's not on-topic, but it's strongly related to ham radio and RF circuitry.
Reading Hayward's classic "Solid State Design for the Radio Amateur" and looking for inspiration, I came across the…

What is the difference between an RF amplifier's DC or quiescent operating point and the RF operating point?
I chose the resistor values in the following schematic to set the DC bias point of VCE=6V and IC=5mA because the transistor data sheet gave the S-parameters at 162MHz for these values. I learned how to do this by studying the book "Rf Circuit…

What is the difference between Rf Gain Blocks & IF Gain Blocks?
As advertised on websites of large manufacturers like Analog Devices And Texas Instruments
I am aware of the difference between an IF stage and an RF stage, however, I was curious if there was any any other differences. Say I have a 50-500MHz IF…

What is an optimal amplifier arrangement with ham radios?
As I am settling on a design for a radio I need to figure out one thing:
Should I modulate on low power and boost it up with a post amp, or should I go on full power right out of the gate?

How can I reduce power consumption and thermal dissipation in power amp?
I am designing a Class-E power amplifier in UHF band using ADS. Now I have 20dBm fundamental output power with 13% PAE, which is low for this class of PA. The problem is that I have thermal dissipation and DC power consumption and harmonics. How…

audio amplifier as fm amplifier possible?
Is it possible? I know it depends on legal issues; it is just for testing.
I will "transmit" from RPI (Raspberry pi as fm transmitter).
