SMT-packaged MMIC band-pass tunable filters from Hittite
Hittite has introduced five SMT-packaged MMIC band-pass tunable filters which are ideal for pre-selection applications in wideband test and measurement equipment, communication systems, and electronic warfare (EW) subsystems up to 37.0 GHz. These analog-tuned MMIC filters are insensitive to environmental conditions, while their small physical size provides a superior alternative to competing resonant cavity and MEMS solutions.
The HMC894LP5E, HMC895LP4E, HMC896LP4E, HMC898LP4E, and HMC899LP4E are tunable MMIC Band-Pass Filters (BPF) which enable continuously variable selection of the filter pass-band based on an analog control voltage from 0 to +14 V. Depending on the product selected and the frequency of operation, the pass band frequency can be tuned from 1 to 37 GHz, while the 3 dB filter bandwidth ranges from 6% to 35%.
The HMC894LP5E, HMC895LP4E, HMC896LP4E, HMC898LP4E, and HMC899LP4E are fabricated in a monolithic process which makes them insensitive to microphonics, while exhibiting very fast tuning of 200 ns. Compared to physically-large switched filter banks and cavity-tuned filters; these compact SMT-packaged filters can save as much as 90% of the required printed circuit board area. Return losses for this filter family are typically better than 10 dB, with residual phase noise of -160 dBc/Hz at 1 MHz offset.
