Chelmsford, Mass. Hittite Microwave Corp. has released a family of GaAs InGaP HBT MMIC VCOs with half frequency and divide-by-4 outputs that provide continuous frequency coverage from 8.45 to 13.9 GHz.
The new line includes the HMC510LP5 (E), HMC534LP5 (E), HMC583LP5(E), and HMC584LP5 (E) VCOs that integrate resonators, negative resistance devices, and varactor diodes. Designed with a monolithic structure, each of these VCOs are said to exhibit excellent phase noise performance up to -116 dBc/Hz at 100 kHz over temperature, shock and process variations.

The power output ranges from +10 to +13 dBm from a +5-V supply voltage, and the prescaler and RF/2 functions may be disabled to conserve current if they are not required. These products are complete, wide frequency range VCOs that require no external matching components.
Available in compact, leadless QFN 5 x 5 mm footprint compatible surface-mount packages, they are suitable for a wide range of applications including point-to-point/multipoint radio, SATCOM, military and test equipment applications.
Samples and evaluation PC-boards for all SMT packaged products are available from stock and can be ordered via the company's e-commerce site or direct via purchase order.
