Nowadays, laterally diffused metal oxide semiconductor (LDMOS) transistors are widely used for RF Power Amplification and in many applications. A simplified circuit of an LDMOS amplifier bias circuit ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

Aimed at X-band radar, 1222 is a 200W 9 to 10GHz pulse amplifier from Empower RF Systems of California. Measuring ~178 x 102 x 25mm, it can deliver pulses up to 500μs long and duty cycles up to 20%.

In just a few years’ time, so many things about wireless communication will be different from the way we know them today. Cellular networks, for example, traditionally made up primarily of larger base ...

Custom RF and microwave solutions deliver high performance, reliability, and durability for defense applications, supporting advanced systems across airborne, maritime, and ground environments up to ...
