Hittite Adds Three New PLL with Integrated Microwave VCO Products

For Immediate Release

Still the Industry's Only Integrated Fractional-N PLL/VCOs to 13.4 GHz!

Chelmsford, MA 01/06/2012 -

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced three new SMT packaged PLLs with Integrated Voltage Controlled Oscillators (VCOs) which are ideal for demanding small form factor applications including microwave/millimeterwave radios, test equipment, fiber optic communications, military subsystemssensors to 13.4 GHz.

The , are full-featured fractional-N PLL frequency synthesizers with integrated microwave VCOs which provide output frequency coverage from 8.45 to 10.8 GHz. These new products offer low open loop phase noise of -140 dBc/Hz at 1 MHz offset, a 350 MHz reference path inputa 14-bit reference divider. The advanced delta-sigma modulator design in the fractional synthesizer enables ultra-fine fractional step sizes while achieving industry leading phase noisespurious emission performance. The highly integrated architecture delivers a rich feature-set including; external triggering, double-buffering, exact frequency generation with 0 Hz frequency error, frequency modulation, phase modulationmore. The , PLL/VCOs are housed in leadless QFN 6 x 6 mm surface mount packagesdeliver up to +12 dBm output power, making them ideal for directly driving the LO port of many of Hittite's high linearity, double-balancedI/Q mixer/receiver products.

In order to minimize design timeresources, Hittite offers an advanced Evaluation Kit to support each PLL/VCO product. Each kit includes an evaluation board with an on-board reference oscillatorvoltage regulators,supports universal loop filter configurations. Included software allows the user to programobserve full performancefunctionality of the PLL/VCO. Hittite's proprietary PLL Design Software Suite enables users to simulatepredict the effect of any parameter on the performance of the PLL/VCO.

Hittite's line of PLL/VCO products uniquely combine the attributes of low phase noise, low spurious, advanced featurescompact size. Samplesevaluation PC boards for all SMT packaged products are available from stockcan be ordered via the company's e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
