General Description
The HMC1197LP7FE 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 HMC1197LP7FE 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 HMC1197LP7FE 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 HMC1197LP7FE 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 HMC1197LP7FEs 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
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.
