Quadrature Modulator IC
(With 1.0 GHz Up-converter)
MB54609
s
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.
s
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

ABSOLUTE MAXIMUM RAGINGS (See WARNING)
WARNING: Exceeding any of the above Absolute Maximum Ratings may cause permanent damage to the LSI.
For normal operation, the device should be used under the recommended operating conditions.
Exceeding any of the recommended conditions may adversely affect LSI reliability.
Note: Although the MB54609 contains an antistatic element to prevent electrostatic breakdown and the circuitry
has been improved in electrostatic protection, observe the following precautions when handling the device:
· When storing or carrying the device, put it in a conductive case.
· Before handling the device, check that the jigs and tools to be used have been uncharged (grounded) as
well as yourself. Use a conductive sheet on the working bench.
· Before fitting the device into or removing it from the socket, turn the power supply off.
· When handling (such as transporting) the MB54609 mounted board, protect the leads with a conductive
sheet.
