Power Amplifiers in Parallel for Higher Output Power – Hybrid Power Combining

By |2018-09-04T14:55:56+00:00August 9th, 2018|Product Development, RF Amplifier|

Recently, we had a customer reach out to us inquiring about a 200 W L-band power amplifier (PA). While we did not have such an amplifier to offer (not yet, anyway), we did have a solution. That solution was four of our new L60T01 amplifiers in a hybrid configuration.   The concept of hybrid or [...]

What is Noise Figure and How to Improve it with a Low Noise Amplifier

By |2018-07-16T19:58:42+00:00July 16th, 2018|Product Development|

Noise Figure (NF) describes the amount of noise a component, amplifier, or an entire radio receive chain contributes to the RF signal being received. Electrical noise is combined with the RF signal as it is generated by the RF transmitter and propagated through space. This signal is then captured by the receiving antenna and guided [...]
