HMC7891 Analog Devices, Inc. (ADI)
RF Limiting Amplifier Module
MFG Part Number: HMC7891
Enlarge Photo

The HMC7891 is a limiting amplifier that operates over the band of 2 GHz to 18 GHz, with a high 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 amplifier can also be used as a frequency tripler due to the high third harmonic output level at saturation. See Figure 14 for a plot of third harmonic levels with input signals from 2 GHz to 6 GHz with an input drive level of 10 dBm.

An integrated voltage regulator provides the 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.
