Overview
FUJITSU SEMICONDUCTOR DATA SHEET DS04-23509-1E ASSP BIPOLAR for Telephone 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 Ω 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 s PACKAGE 20-pin Plastic SSOP (FPT-20P-M03) 1 MB54609 s PIN ASSIGNMENT (TOP VIEW) RFout 1 20 PS GND 2 19 GND LO2 3 18 Q GND 4 17 XQ XIF 5 16 XQMOD IF 6 15 QMOD LO1 7 14 XI XLO1 8 13 I GND 9 12 GND V CC 10 11 V CC (FPT-20P-M03) 2 MB54609 s PIN DESCRIPTION Pin no.
