Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has released a new Broadband High IP3 Dual Channel Downconverter which operates from 700 to 3500 MHz. The HMC990LP4E is ideal for space constrained frequency conversion applications in wireless infrastructure equipment such as base transceiver stations, remote radio units and small cells.

The HMC990LP4E, high linearity, dual channel downconverting mixer is optimized for multi-standard diversity receiver applications which require low power consumption and small size. This highly integrated RFIC features new wideband limiting LO amplifiers to achieve an unprecedented RF bandwidth of 700 MHz to 3500 MHz. Unlike conventional narrow-band downconverter RFICs, the HMC990LP4E supports both high-side and low-side LO injection over the entire RF frequency band.

The HMC990LP4E integrates LO and IF amplifiers, LO and RF baluns and wideband passive mixer cores with bias control. The unique architecture of this dual channel converter provides excellent LO/RF, LO/IF, and RF/IF isolations, while the RF and LO input ports are internally matched to 50Ω. Ideal for demanding high linearity applications, the HMC990LP4E exhibits a very low noise figure of 9 dB with high input IP3 of +25 dBm. For narrow-band applications, the input IP3 performance of the HMC990LP4E can be further optimized with simple external matching.

Housed in a compact RoHS compliant, 4 x 4 mm plastic QFN package, the HMC990LP4E consumes typically less than 1.5 Watts, while a very fast enable control interface for the LO and IF amplifiers provides additional power conservation options in time division duplex (TDD) applications. 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.
