VCOs - SMT

HMC398QS16G / 398QS16GE
v03.0810

Ku-Band MMIC VCO with DIVIDE-BY-8 14 - 15 GHz

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

Functional Diagram

Pout +7 dBm Phase Noise -105 dBc/Hz kHz Typ. No External Resonator Needed Single Supply 5V 325 mA QSOP16G SMT Package

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

[2] Circuit Board Material Rogers 4350

The circuit board used in the 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.
