Quadrature Modulator IC
(With 1.0 GHz Up-converter)
MB54609
I
DESCRIPTION
The MB54609 is an intermediate-frequency (IF) quadrature modulator IC incorporating a 1.0-GHz up-converter
optimized for use in digital mobile telecommunication systems such as GSM and PDC (Personal Digital Cellular).
The MB54609 incorporates a quadrature modulator for IF modulation, a transmission up-convert mixer, and a
F/F type phase shifter as well, capable of handing IFs in a broad band.
In addition, the MB54609 operates at a low power supply voltage of 3.0 V and a low power supply current of 18
mA (both as typical values), contributing to saving the power consumption of the device.

FEATURES
Incorporating a high-performance transmission mixer covering the entire frequency band of up to 800 MHz used
for PDC services (Maximum output frequency of 1.1 GHz)
Maximum output frequency: 1.1 GHz, Output level: –9 dBm (typical)
Externally connecting the quadrature modulator with the transmission mixer, allowing a bandpass filter (BPF)
to be inserted in between
The quadrature modulator output can drive a 50
load.
Flip-flop phase shifter capable of handling intermediate frequencies in the broad band (100 to 800 MHz)
Operation at low voltage: 2.7 to 3.0 to 3.3 V
Low current consumption
During operating: 18.0 mA (typical)
In power save mode: 0.6 mA (typical)
Operating temperature range: Ta = –20 to +85°C
