The HMC892LP5E/HMC893LP5E/HMC897LP4E tunable bandpass filters are ideal for preselection in multiband communication systems, wideband radar, and in test and measurement equipment. The HMC892LP5E filter center frequency is adjustable from 4.0 to 7.7 GHz, while the HMC893LP5E and HMC897LP4E filter center frequency is adjustable over an octave bandwidth of 4.8 to 9.5 GHz and 9.0 to 19.0 GHz, respectively.
All parts have two independent voltage controls for adjustment of passband frequency and bandwidth Pass-bandwidth for the HMC892LP5E and HMC893LP5E is adjustable to ±3% of filter center frequency. Return loss for all three is better than 10 dB across the operating frequency, and the wideband rejection is at least 30 dB out to 40 GHz. The HMC892LP5E and the HMC893LP5E are available in compact, RoHS-compliant 5 x 5-mm QFN SMT plastic packages and are specified for operation from –40° to 85°C. The HMC897LP4E is available in a compact RoHS-compliant 4 x 4-mm QFN SMT plastic package. (HMC892LP5E, $98 ea/10 — available now.)
