Hittite's New Cellular Transceiver RFICs Energize Wideband Infrastructure
November 7, 2012 Press Release
-- Highly Integrated Solutions offer High Linearity and Low Power Consumption!
Chelmsford, MA 11/07/2012 -
Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication &
military markets, has released a new Receiver (Rx) and Transmitter (Tx) Radio Frequency Integrated Circuit (RFIC)
chipset which is ideal for frequency conversion applications in wireless infrastructure equipment such as base
transceiver stations, remote radio units, small cells and repeaters from 700 – 3500 MHz.
HMC1190LP6GE is a high linearity Dual
Channel Downconverter with Integrated PLL/VCO which operates from 700 to 3500 MHz and is designed specifically for
multi-standard receiver applications that require a compact and low power solution. The
HMC1190LP6GE delivers 8 dB conversion
gain, with excellent IP3 and input P1dB performance of +24 dBm and +11 dBm respectively. In support of high IF
receivers and antenna diversity architectures, 2 x 2 spurious products are typically below -70 dBc. The
HMC1190LP6GE RF and LO inputs are
single-ended while an enable/disable pin makes it possible to reduce power consumption dynamically as conditions
allow. Balanced high linearity passive mixer cores combined with high-linearity IF amplifiers deliver excellent
LO-to-RF, LO-to-IF, and RF-to-IF isolations.
For transmit applications, the
HMC1197LP7FE is a low noise, high
linearity Direct Quadrature Modulator with integrated Fractional-N PLL/VCO which is rated for operation from 100
to 4000 MHz. This wideband transmitter solution delivers very high output IP3 of +30 dBm, with up to +10.5 dBm of
output power and a very low noise floor of -160 dBm/Hz. The single-ended RF output port is matched to 50 Ohms with
no external components while the auxiliary LO output enables the
HMC1197LP7FE to distribute identical
frequency and phase signals to multiple destinations within the transmitter or receiver. An integrated
programmable bandwidth Low Pass Filter (LPF) in the LO path ensures little or no LO contribution to modulator
sideband rejection. Sixteen programmable LPF bands enable true wideband operation and allow agile LO frequency
filtering for different band plans during and after deployment.
HMC1197LP7FE incorporate a feature-rich,
industry leading PLL and wideband VCO. The PLL features a very low Figure of Merit (FOM) of -230 dBm/Hz in integer
mode, while the internal VCO section can generate frequencies from 50 to 4100 MHz. The integrated Phase Detector
(PD) and delta-sigma modulator within the
HMC1190LP6GE and HMC1197LP7FE
are capable of operating at up to 100 MHz permitting wider loop-bandwidths with excellent spectral performance.
The PLL/VCO section can phase adjust and synchronize multiple Hittite Tx and Rx RFICs enabling scalable MIMO and
beam-forming radio architectures. Additional PLL/VCO features include a configurable output mute function, and an
Exact Frequency Mode that enables both products to generate fractional frequencies with 0 Hz frequency error and
the ability to synchronously change frequencies without changing the phase of the output signal.
