| HMC398QS16G / 398QS16GE v02.0805 Ku-Band MMIC VCO with DIVIDE-BY-8, 14.0 - 15.0 GHz Typical Applications Low noise MMIC VCO w/Divide-by-8 for Ku-Band applications such as: * Point-to-Point Radios * Point-to-Multi-Point Radios / LMDS * VSAT Features Pout: +7 dBm Phase Noise: -105 dBc/Hz @100 KHz Typ. No External Resonator Needed Single Supply: 5V @ 325 mA QSOP16G SMT Package 9 VCOs & PLOs - SMT Functional Diagram 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 Electrical Specifications, TA = +25 C, Vcc1, Vcc2 = +5.0V Parameter Frequency Range Power Output SSB Phase Noise @ 100 kHz Offset, Vtune= +5V @ RF Output Tune Voltage Supply Current Tune Port Leakage Current (Vtune= 10V) Output Return Loss Harmonics/Subharmonics 1/2 3/2 2nd 5/2 2 -20 -30 -12 -40 4 30 1.5 Vtune Icc 1 (Digital) Icc 2 (RF) 1.0 65 260 10 RF Output Divided Output +3 -9 Min.
