SiGe WIDEBAND

DOWNCONVERTER, 0.8 - 2.7 GHz

v00.0407

General Description

Features

Functional Diagram

The HMC334LP4 & HMC334LP4E are low noise,

wideband downconverter RFICs which are ideal

for Cellular/3G and WiMAX/4G applications from

0.8 to 2.7 GHz. The LO input accepts drive levels

from -6 to +6 dBm while the RFIC provides 48 dB of

LO to RF isolation, and 0 dB conversion loss. The

HMC334LP4(E) will support an IF output bandwidth

of up to 600 MHz and consumes only 173mA from

a +5.0V supply. This wideband active mixer also

provides excellent performance in the presence of

high level “Blocker” signals, making it ideal for receiver

applications in demanding environments.

Conversion Loss: 0 dB

LO to RF Isolation: 48 dB

Single-Ended LO Drive: -6 dBm

Input IP3: +26 dBm

SSB Noise Figure: 10.5 dB
