HMC-C028

HMC-C028 v01.1007 WIDEBAND VCO w/ BUFFER AMPLIFIER MODULE, 4 - 8 GHz 12 CONNECTORIZED MODULES - VCOs Features Wide Tuning Bandwidth High Output Power: +20 dBm Low SSB Phase Noise: -95 dBc/Hz @100 kHz No External Resonator Needed Single Positive Supply: +8 to +15V @ 185 mA Typical Applications The HMC-C028 VCO Module is ideal for: • Industrial/Medical Equipment • Test & Measurement Equipment • Military Radar, EW & ECM • Lab Instrumentation RoHS Compliant Hermetically Sealed Module Field Replaceable SMA Connectors -40°C to +85°C Operating Temperature General Description The HMC-C028 is a wideband GaAs InGaP Voltage Controlled Oscillator which incorporates the resonator, negative resistance device, and varactor diode. An internal voltage regulator provides excellent 0.2 MHz/V frequency pushing while the output buffer amplifier boosts output power to +20 dBm; which is enough to drive one or two mixers. Phase noise performance is excellent over temperature due to the oscillator’s monolithic construction. The Vtune port accepts an analog tuning voltage from 0 to +18V. The HMC-C028 VCO operates from a single +8V to +15V supply, and is housed in a hermetically sealed module. This wideband VCO uniquely combines the attributes of small size, low phase noise, wide tuning range and high output power.
