v01.0402 MICROWAVE CORPORATION HMC401QS16G Ku-BAND MMIC VCO with DIVIDE-BY-8, 13.2 - 13.5 GHz Typical Applications Features Low noise MMIC VCO w/Divide-by-8 for Ku-Band applications such as: Pout: -7 dBm • Pt to Pt Radios No External Resonator Needed • Multi-Pt Radios / LMDS Single Supply: 5V @ 290 mA • VSAT QSOP16G SMT Package Functional Diagram General Description Phase Noise: -105 dBc/Hz @100 KHz Typ. The HMC401QS16G is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO. The HMC401QS16G integrates a resonator, negative resistance device, varactor diode and 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. 15 VCOs - SMT Electrical Specifications, TA = +25° C, Vcc1, Vcc2 = +5V Parameter Min.

U1 HMC401QS16G VCO PCB* 104436 Eval Board The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads and backside ground slug should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
