UHF to mmWave Cavity Filter Solutions

Cavity Filters 300 Mhz to 50 GHz

High Rejection & Selectivity

Cavity filters achieve much higher Q, steeper rejection skirts, and higher power handling than other filter technologies, such as ceramic resonator filters, and are utilized where low passband insertion loss and high rejection of neighboring channels/spurious emissions are critical. Applications include military and commercial fixed site and mobile networks, as well as satellite communications.

Measurement of Amplifier Additive Phase Modulation Noise (APM)

Part 1: Background & Theory

Optimum APM Test Configuration

In the efforts to properly characterize the Additive Phase Modulation Noise (APM) and Additive Amplitude Modulation Noise (AAM) performance of MMIC amplifiers in the lab, it is important to consider the performance capabilities and limitations of phase noise analyzer and test setup (see Figure 4).  Both APM and AAM performance can be dependent upon the analyzer’s internal signal source carrier frequency, power level, and, importantly, the phase length from signal source output to RF input, so great care must be taken to optimize these parameters.
