General Description
The HMC398QS16G & HMC398QS16GE are single chip GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC398QS16G & HMC398QS16GE integrate resonators, negative resistance devices, varactor diodes and divide-by-8 prescalers. 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 & HMC398QS16GE require no external components
