Wideband Downconverter RFIC is Ideal For Multi-Standard Diversity Receivers!

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has released a new Broadband High IP3 Downconverter RFIC which operates from 700 to 3500 MHz. The HMC1090LP3E is ideal for space constrained frequency conversion applications in wireless infrastructure equipment such as base transceiver stations, remote radio units, small cells and repeaters.

The HMC1090LP3E is a high linearity downconverting mixer which is optimized for multi-standard diversity receiver applications where low power consumption and small size are required. This highly integrated RFIC features a wideband limiting LO amplifier and can be used in any 3GPP operating band from 700 to 3500 MHz. Unlike conventional narrow-band downconverter RFICs, the HMC1090LP3E supports both high-side and low-side LO injection over the entire RF band.

The HMC1090LP3E integrates LO and IF amplifiers, LO and RF baluns and a wideband passive mixer core with bias control. The unique architecture of this converter provides excellent LO/RF, LO/IF, and RF/IF isolations, while the RF and LO input ports are internally matched to 50Ω. The HMC1090LP3E exhibits noise figure as low as 8.5 dB and input IP3 up to +26 dBm making it ideal for demanding high linearity applications. For narrow-band applications, the input IP3 performance of the HMC1090LP3E can be further optimized with simple external matching.

Consuming only 0.9W of DC power, the HMC1090LP3E offers a very fast enable function which provides additional power conservation options in time division duplex (TDD) applications. The HMC1090LP3E is housed in a compact RoHS compliant, 3 x 3 mm plastic QFN package. The unique converter is also available in dual channel format as the HMC990LP4E.
