Band-Reject MMIC Filter Offers Fast Tuning and Octave Tuning Bandwidth

The HMC1000LP5E is a Tunable Band Reject Filter which exhibits only 3 dB of insertion loss within its passband of 100 MHz to 25 GHz. The band rejection frequency is user selectable, and can be varied between 3.6 and 12.2 GHz, while the -20 dB filter bandwidth can be varied from 6 to 14 %. The HMC1000LP5E offers four different stop band tuning modes, and is controlled by two analog tuning voltages between 0 and +14V. Furthermore, by virtue of its monolithic implementation, the HMC1000LP5E exhibits excellent immunity to vibration and microphonics.

The HMC1000LP5E delivers fast tuning speed of 200 ns, and provides a dynamically adjustable solution in advanced communications applications. This unique, non-reflective tunable filter exhibits good return loss in the passband as well as the stop band, and delivers very low residual phase noise of -162 dBc/Hz. The HMC1000LP5E is a solid state solution and is a much smaller alternative to physically large, mechanically tuned filter implementations.

The HMC1000LP5E is housed in a compact, RoHS compliant 5 x 5 mm QFN SMT plastic package. 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.
