Tunable band-reject MMIC filter is industry’s first

Offered by the company to be the industry’s first of its kind, the HMC1000LP5E MMIC tunable band-reject filter is ideal for absorbing unwanted signals in test and measurement equipment, signal-processing equipment, and electronic warfare subsystems up to 25 GHz. The device exhibits only 3 dB of insertion loss within its passband of 100 MHz to 25 GHz. The band-rejection frequency is user selectable, and can be varied between 3.6 and 12.2 GHz, while the –20-dB filter bandwidth can be varied from 6% to 14%.

The filter also offers four different stopband tuning modes, and is controlled by two analog tuning voltages between 0 and 14 V. Housed in a compact RoHS-compliant 5 x 5-mm QFN SMT plastic package, the HMC1000LP5E delivers fast tuning speed of 200 ns and provides an adjustable solution in advanced communications applications. This non-reflective tunable filter exhibits good return loss in the passband as well as the stopband, and delivers very low residual phase noise of –162 dBc/Hz.
