 HMC-C029
v00.1206
WIDEBAND VCO w/ BUFFER AMPLIFIER MODULE, 5.0 - 10.0 GHz
Features
Wide Tuning Bandwidth High Output Power: +20 dBm Low SSB Phase Noise: -93 dBc/Hz @100 kHz No External Resonator Needed Single Positive Supply: +8V to +15V @ 195 mA
Typical Applications
The HMC-C029 VCO Module is ideal for: * Industrial/Medical Equipment * Test & Measurement Equipment * Military Radar, EW & ECM * Lab Instrumentation
RoHS Compliant Hermeticaly Sealed Module Field Replaceable SMA Connectors -40C to +85C Operating Temperature
General Description
The HMC-C029 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 +20V. The HMC-C029 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.
