Functional Diagram

General Description

The HMC485MS8G & HMC485MS8GE are high dy-

namic range passive MMIC mixers with integrated

LO ampliﬁer in plastic surface mount 8 lead Mini

Small Outline Packages (MSOP) covering 1.7 to 2.4

GHz. Excellent input IP3 performance of +34 dBm

for down conversion and +27 dBm for up conver-

sion 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 lev-

els. 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 HMC485MS8G(E) input IP3

performance coupled with its high P1dB rivals tradi-

tional active FET mixers while offering a much smaller

14.8mm²standard IC footprint.

Electrical Speciﬁcations, T_A= +25°C, LO = 0 dBm, IF = 200 MHz*, Vdd= 5V
