HMC398QS16GETR

Overview

The HMC398QS16GETR is a Ku-Band Voltage Controlled Oscillator (VCO) designed for VSAT applications, operating within the 14 GHz to 15 GHz frequency range. It integrates a resonator and utilizes GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC technology. The device features a divide-by-8 output configuration and is housed in a 16-pin QSOP-EP surface mount package.

Feature Summary

• Integrates a resonator within a single chip GaAs InGaP HBT MMIC structure
• Designed specifically for Ku-Band Very Small Aperture Terminal (VSAT) systems
• Provides a divide-by-8 output signal configuration

Applications

• Ku-Band VSAT communication systems
• Satellite uplink/downlink modules
• Microwave radio frequency generation circuits

Procurement Notes
