W3011

1 GHz Quadrature Modulator

modulation of an RF carrier by I & Q baseband

inputs. It is particularly suited for use in mobile and

handheld cellular telephones designed to the IS-136

(North American 824 MHz to 849 MHz), PDC

(Japan RCR-STD27 889 MHz to 958 MHz), and

other digital personal-communications standards.

Features

+ Guaranteed performance at 2.7 V power supply

+ Output power of 3 dBm into 50 W load (single-

ended) with 3 V operation

+ Direct RF modulation with or without offset mixer

+ Automatic power control (APC) capability

+ Accurate 90° phase shifter for carrier

The circuit block diagram is shown in Figure 1. From

two LO signals, LOL and LOH, the offset mixer

produces an internal LO signal, which prevents the

external VCOs from being pulled by the large

transmitted signal. The phase shifter splits the LO

signal into two carriers with 90° phase separation

and equal amplitude.

+ Double-balanced active mixers minimize carrier

feedthrough (origin offset)

+ Low-current sleep mode

These signals are fed to the in-phase (I) and

quadrature-phase (Q) double-balanced mixers. The

resulting signals are summed and fed into the output

amplifier. This amplifier can provide 0 dBm linear

output power, minimum, into a 50 W load.

Applications

+ PDC 800 and American digital cellular mobile

terminals

The output power can be attenuated up to 50 dB by

applying a control voltage to the APC input.

Nominally, the output power is at maximum

(+3 dBm) with VAPC > 2.2 V, and at minimum

(–50 dBm) with VAPC < 0.8 V.

+ Cellular base stations

Description

A CMOS/TTL-compatible logic input allows the

device to be put into a powerdown mode in which

less than 10 µA of supply current is consumed.
