Cost Effective Full-Duplex Systems Utilizing a Semi-Custom Approach

By |2019-05-02T18:25:16+00:00May 2nd, 2019|Design Innovation, Product Development|

The requirements of modern datalinks in the UAV and large airframe market present challenges for systems designers. Many modern communication systems often require full-duplex operation, and several systems may be operating on a single airframe. At the same time size, aerodynamic and radar signature concerns can limit the ability of designers and integrators to add [...]

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

By |2019-04-22T18:32:23+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 |2019-04-18T17:40:20+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 [...]
