Hittite Launches New Ultra-Compact Tunable Filter Product Line!
Low-Pass and Band-Pass MMIC Filters in a 5 x 5 mm SMT package
MA, 03/05/10 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for
communication & military markets, has introduced its 25th product line, tunable filters, which are ideal for
pre-selection in multi-band communication systems, wideband radar, and in test and measurement equipment. Tunable
over a 1.0 GHz to 7.6 GHz frequency range, these four new, ultra-compact, varactor-tuned, MMIC filters are
inherently stable and their small physical size and insensitivity to environmental conditions provide a superior
alternative to competing resonant cavity and MEM solutions.
HMC882LP5E are tunable, seventh-order, low-pass filters (LPF) with adjustable cut-off from 2.2 GHz to 4.0 GHz,
and from 4.5 GHz to 7.6 GHz, respectively. A 0 V to 14 V control signal provides very fast and continuous
adjustment of passband cut-off: 5000 GHz/millisecond. The LPFs maintain stopband rejection of at least 35 dB out
beyond 30 GHz.
HMC891LP5E are tunable, third-order, band-pass filters (BPF) with two independent voltage controls for
adjustment of pass-band frequency and bandwidth. Filter center frequency is adjustable from 1.0 GHz to 2.0 GHz,
and from 2.0 GHz to 3.9 GHz, respectively. Pass-bandwidth is adjustable to ±3% of filter center frequency. Like
the companion low pass filters, return loss is 10 dB and the BPFs maintain stop-band rejection of at least 30 dB
out to 9 GHz.
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 www.hittite.com.
