Hittite introduces a Heterojunction Bipolar Transistor (HBT) MMIC VCO with an integrated divide-by-8 prescaler packaged in a low cost, surface mount 16 leaded QSOP package with an exposed base for improved RF and thermal performance. The HMC401QS16G features a Pout of > -8 dBm from a 5 V supply, SSB Phase Noise of -110 dBc/Hz @ 100 kHz, and no external resonator is needed. The VCO's phase noise is excellent over temperature, shock, and process due to its monolithic structure. The HMC401QS16G is ideal for usage in LMDS, point-to-point radios and VSAT applications.
