Overview

Input IP3: +34 dBm
Conversion Loss: 9 dB
Low LO Drive: -2 to +4 dBm

Single Positive Supply: 5V @ 45 mA
Ultra Small MSOP Package: 14.8mm²

The HMC485A(E) is a high dynamic range passive MMIC mixer with an integrated LO amplifier in a plastic surface mount 8 lead Mini Small Outline Package (MSOP) covering 1.7 to 2.4 GHz. Excellent input IP3 performance of +34 dBm for down conversion and +27 dBm for up con-version is provided for 2.5G & 3G GSM/CDMA based UMTS or PCS applications at an LO drive of 0 dBm. With an input 1 dB compression of +19 dBm, the RF port will accept a wide range of input signal levels.

Conversion loss is 9.2 dB typical. The 50 to 300 MHz IF frequency response will satisfy many UMTS/PCS transmit or receive frequency plans configured for low side LO. The HMC485A(E) input IP3 performance coupled with its high P1dB rivals traditional active FET mixers while offering a much smaller 14.8mm² standard IC footprint.
