The HMC1197LP7FE from Hittite is a low-noise, high-linearity direct quadrature modulator with fractional-N PLL and VCO which is ideal for digital modulation applications from 0,1 to 4,0 GHz including cellular/3G, LTE/WiMAX/4G, broadband wireless access and ISM circuits.
Housed in a compact 7 x 7 mm (LP7) SMT QFN package, the device requires minimal external components and provides a low-cost alternative to more complicated double up-conversion architectures. The RF output port is single-ended and matched to 50 Ω with no external components.
Auxiliary LO output (differential or single-ended), enables the HMC1197LP7FE to distribute identical frequency and phase signals to multiple destinations. Individual gain settings ensure optimal signal levels tailored to each output.
An external VCO input allows the IC to lock external VCOs, and enables cascaded LO architectures for MIMO radio applications. Two separate charge pump outputs enable separate loop filters optimised for both integrated and external VCOs, and seamless switching between integrated or external VCOs during operation.
A programmable RF output phase feature can further phase adjust and synchronise multiple HMC1197LP7Fes, enabling scalable MIMO and beam-forming radio architectures.
An 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 HMC1197LP7FE to generate fractional frequencies with 0 Hz frequency error and the ability to synchronously change frequencies without changing the phase of the output signal.
