Hittite Adds Five New Tunable MMIC Filters for Frequencies to 37 GHz
-- Band-Pass MMIC Filters Can Save up to 90% of PC Board Space
MA, 10/04/2011 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for
communication & military markets has introduced five new 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.
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 +14V. 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%
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.
HMC894LP5E, is housed in a
compact, RoHS compliant 5 x 5 mm QFN SMT plastic package, while the
HMC898LP4E, and the
are housed in RoHS compliant 4 x 4 mm QFN SMT plastic packages.
Samples and evaluation PC boards for all
SMT packaged products are available from stock and can be ordered via the company's e-commerce site or via direct
purchase order. Released data sheets are available on-line at
