Technical Specifications

The HMC637LP5ETR operates over a wide frequency range, typically from 24 to 32 GHz for RF and IF, and uses a sub-harmonic LO at half the desired LO frequency. It exhibits a low conversion loss, typically around 10 dB, and high LO to RF and LO to IF isolation, typically greater than 30 dB. The input IP3 is typically around +15 dBm. It is packaged in a compact 5x5 mm QFN leadless package for surface mount assembly. Specific frequency ranges, conversion loss values, and isolation performance are detailed in the Analog Devices datasheet.
