The HMC398QS16G(E) is a single chip GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO. The HMC398QS16G(E) integrates a resonator, negative resistance device, varactor diode and a divide-by-8 prescaler. The VCO’s phase noise performance is excellent over temperature, shock, and process due to the oscillator’s monolithic structure. Power output is +7 dBm typical from a 5V supply voltage. The voltage controlled oscillator is packaged in a low cost, surface mount 16 leaded QSOP package with an exposed base for improved RF and thermal performance. The HMC398QS16G(E) requires no external components.ApplicationsPoint-to-Point RadiosPoint-to-Multi-Point Radios / LMDSVSAT
