MEMS-Based Amplified Switch Filter Bank

Spectrum Microwave (Delmar, DE) offers a MEMS-based amplified switch filter bank that maintains a high linearity over multi-octave bandwidth, with the lowest possible current consumption. This 9-channel system features a very low passband noise figure and moderate linear gain, thereby maximizing the dynamic range. The filter bank is designed specifically for RF and microwave applications that demand minimum steady-state power consumption, where continuous switching is not necessary.

The device is magnetically self-latching, eliminating the need to consume energy to maintain a selected switch state. It consists of nine user-selectable RF frequency bands from 20-500 MHz, and features a filter-amplifier-filter configuration that offers low distortion amplification of the input signal. The unit requires a single +3.3 VDC power supply and can withstand hot switching with a rated lifetime of 100 million cycles.
