The HMC700LP4(E) is a SiGe BiCMOS fractional-N frequency synthesizer. The synthesizer includes a very low noise digital phase frequency detector (PFD), and a precision controlled charge pump.The fractional synthesizer features an advanced deltasigma modulator design that allows both ultra-fine step sizes and very low spurious products. Spurious outputs are low enough to eliminate the need for costly Direct Digital Synthesis (DDS) references in many applications.The HMC700LP4(E) phase-frequency detector (PFD) features cycle slip prevention (CSP) technology that allows faster frequency hopping times.Ultra low in-close phase noise and low spurious also permit architectures with wider loop bandwidths for faster frequency hopping and low micro-phonics. FSK mode allows the synthesizer to be used as a simple low cost direct FM transmitter source.Applications Base Stations for Mobile Radio WiMAX Test & Measurement CATV Equipment Phased Array Applications Simple FSK Links DDS Replacement

The HMC1197 is a low noise, high linearity Direct Quadrature Modulator with Fractional-N PLL&VCO RFIC which is ideal for digital modulation applications from 0.1 to 4.0 GHz including; Cellular/3G, LTE/WiMAX/4G, Broadband Wireless Access & ISM circuits housed in a compact 7x7 mm (LP7) SMT QFN package, the HMC1197 RFIC requires minimal external components & provides a low cost alternative to more complicated double upconversion architectures. The RF output port is single-ended and matched to 50 Ohms with no external components.Auxiliary LO output (differential or single-ended), enables the HMC1197 to distribute identical frequency and phase signals to multiple destinations. Individual gain settings ensure optimal signal levels tailored to each output.External VCO input allows the HMC1197 to lock external VCOs, and enables cascaded LO architectures for MIMO radio applications. Two separate Charge Pump (CP) outputs enable separate loop filters optimized for both integrated and external VCOs, and seamless switching between integrated or external VCOs during operation. Programmable RF output phase feature can further phase adjust and synchronize multiple HMC1197s enabling scalable MIMO and beam-forming radio architectures.Integrated programmable Low Pass Filter (LPF) on the modulator LO input ensures no LO harmonic contribution to modulator sideband rejection performance. Sixteen programmable LPF bands enable true wideband operation, eliminating the need for external band specific harmonic filtering hardware.Additional features include configurable LO output mute function. Exact Frequency Mode that enables the HMC1197 to generate fractional frequencies with 0 Hz frequency error and the ability to synchronously change frequencies without changing the phase of the output signal.
