Hittite Introduces Industry Leading Wideband PLL with Integrated VCO

April 14, 2011

Excellent for Low Phase Noise, Spurious Free, High SNR Applications

Chelmsford, MA, 04/14/2011 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets has introduced the HMC830LP6GE, an industry leading low noise, wide band, Fractional-N Phase-Locked-Loop (PLL) with integrated Voltage Controlled Oscillator (VCO). It is capable of generating continuous frequencies from 25 MHz to 3000 MHz. The HMC830LP6GE features industry leading phase noise and spurious performance across all frequencies, making it the best choice for applications that require excellent signal quality performance and high SNR.

The HMC830LP6GE also features an integrated Phase Detector (PD) and delta-sigma modulator which are capable of operating at up to 100 MHz to permit wider loop-bandwidths with excellent spectral performance. With its superior performance, the HMC830LP6GE is ideal for wideband multi-carrier, multi-standard cellular base stations as it can be used in up or down conversion, as a low jitter clock LO generator, or as a tunable reference source for a spurious free performance. It is also ideal for high QAM microwave point-to-point links, software defined radios and communications test equipment.

The HMC830LP6GE synthesizer Figure of Merit is -230 / -227 in integer and fractional modes respectively. Double sideband RMS jitter is less than 180 fs and the noise floor is -171 dBc/Hz in fundamental mode at 2 GHz. The worst integer boundary spurious product is around -55 dBc when falling in-band. These specifications make the HMC830LP6GE the ultimate choice for designers looking for a single, superior performance, multi-purpose, multi-application device that can cover a wide frequency range.

The HMC830LP6GE is wideband 50 Ohm matched, includes RF output power control from 0 to 9 dB (3 dB steps) and an output mute function. An Exact Frequency Mode enables output frequencies with small channel step sizes, 0 Hz frequency error and zero spurious related to channel spacing.

The HMC830LP6GE is housed in a 6 x 6 mm plastic leadless surface mount package and provides excellent temperature stability over the -40 °C to +85 °C temperature range. 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 via direct purchase order.
