General Description

The PMB 2208 contains a direct

Package

quadrature modulator and an up/down-

conversion mixer with corresponding

bias circuitry.

Features

s Direct quadrature modulator and

up/down-conversion mixer on one

chip

s Modulator:

- LO input frequency range from

200MHz to 550MHz corresponds to

an output frequency range from

100MHz to 275MHz

- Generation of orthogonal carriers

without external elements and with-

out trimming

s

Mixer:

- typ. 48dB carrier suppression with - Double-balanced Gilbert cell

1Vpp baseband level

- typ. 49dB SSB suppression with

- RF and IF frequency range from

DC to 2.5GHz

1Vpp baseband level

- typ 39dB carrier suppression

- typ. 51dB rejection of third-order - Low noise

intermodulation products with 1Vpp

baseband level

s Supply voltage range from 2.7 to

4.5V

- Low output noise floor

s Power-down mode

s Temperature range -30 to 85°C

Application

s Vector-modulated digital mobile s Analog systems with FM and AM

cellular systems, such as GSM,

modulation

PDC-800, PDC-1.5, PHS, DAMPS,

DCS1800, WLAN, etc.

s Space- and power-saving optimi-

zations of existing discrete trans-

s Various modulation schemes, such mitter circuits

as PM, PSK, FSK, QAM, QPSK,

GMSK, etc.
