DRR1-38XX

This digital radio receiver module DRR1-38XX provides the RF receive and down conversion function for 38 GHz digital radios.

DRR1-38XX offers excellent phase noise performance and can be easily phase locked to a frequency reference. The DRR1-38XX is ideal for use in radios using 2 and 4 FSK modulation. The low noise figure is achieved by using the Hewlett-Packard PHEMT MMIC technology coupled with an image reject mixer to minimize the noise figure. The receiver module features an integrated ultra low noise silicon bipolar VCO operating in the S/C band as the local oscillator. A portion of the oscillator output is coupled off and is applied to a frequency divider network. The low frequency output from the frequency divider can be used to phase lock the source. The local oscillator output is applied to a frequency multiplier network to produce the desired LO frequency to the mixer.
