MB54609 - Quadrature Modulator IC

General 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).

Key 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 handlin.

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.
