HMC632LP5E

Overview

The HMC632LP5E is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator (VCO) manufactured by Analog Devices Inc. It operates in the frequency range of 7125 MHz to 7825 MHz with a secondary output at 14250 MHz to 15650 MHz. The device requires a supply voltage between 4.75 V and 5.25 V, drawing up to 400 mA. It features a tuning voltage range of 2 VDC to 13 VDC and delivers a second harmonic level of 25 dBc. Packaged in a QFN-32 SMD enclosure measuring 5.1 mm x 5.1 mm x 1 mm, it functions within an operating temperature range of -40°C to +85°C.

Feature Summary

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to assembly. Check current availability as supply may be limited. Ensure ESD protection protocols are followed during storage and installation to maintain device integrity and operational reliability.

Selection Notes

Select this VCO when a fixed frequency range around 7.1–7.8 GHz is required without external tuning loops. Consider the integrated design for space-constrained applications. Evaluate power consumption against system thermal limits. Verify that the available tuning voltage range matches the control circuit capabilities. Assess package size compatibility with PCB layout constraints.
