Richardson RFPD offers 2- to 18-GHz limiting amplifier from ADI

Aug. 5, 2017

Geneva, IL. Richardson RFPD Inc. announced the availability of and full design support capabilities for a new limiting amplifier module from Analog Devices Inc. The HMC7891 operates from 2 GHz to 18 GHz with a gain of 47 dB. The amplifier provides a saturated output power of +13 dBm over the input power range of −30 dBm to +10 dBm, for a limiting dynamic range of 40 dB. The new amplifier can also be used as a frequency tripler due its high third-harmonic output level at saturation.

An integrated voltage regulator provides proper bias voltage, drawing 300 mA from a single DC power supply of 8 V ±1 V. The HMC7891 is packaged in a compact modular design with field-replaceable SMA connectors.

The HMC7891 limiting amplifier module is suitable for telecom-infrastructure, test-instrumentation, electronic warfare, aerospace, and radar applications. One example is a radar warning-receiver application, wherein the HMC7891’s constant output power would allow for more accurate frequency demodulation.

Additional key features of the HMC7891 include a noise figure of 3.5 dB and an operational temperature range of -40°C to +85°C. The amplifier comes in an ML-4-2 (4-lead module with connector interface) package. For more information visit the HMC7891 webpage.
