Voltage Controlled Oscillators
Hittite announces two SMT packaged MMIC VCOs with integrated buffer amplifiers. The HMC505LP4 covers 6.8 to 7.4 GHz, and delivers +11 dBm of output power, with a SSB phase noise of 106 dBc/Hz at 100 kHz offset. The HMC506LP4 covers 7.8 to 8.7 GHz and offers +14 dBm output power with a SSB phase noise of 103 dBc/Hz at 100 kHz offset. Both VCOs operate from a single +3V supply and integrate the varactor, negative resistance circuit, resonator, and buffer amplifier on a single HBT MMIC. Each product is housed in a standard 4 × 4 mm QFN SMT plastic package with identical PCB assignments.
