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.
HMC891LP5E are available in a compact, RoHS compliant 5 x 5 mm QFN SMT plastic package and are specified for
operation from -40 °C to +85 °C.
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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas
and reference material while performing my work as an RF system and circuit design engineer.
The Internet was still largely an unknown entity at the time and not much was available
in the form of WYSIWYG
