• Modulation and Upconversion from I/Q Baseband to RF on a single chip
• Designed for Global Systems for Mobile (GSM) portable cellular telephones
• Internal voltage-controller oscillator (VCO) and Single-Sideband (SSB) mixer for transmit carrier generation
• Internal RF filter for minimal external parts
• Independent power-up/power-down functions
• Low current consumption at 3.75 Volt operation
• Typical driver amplifier output power: +6 dBm
• Low profile package: 48-pin plastic quad flatpack package
• Three wire serial data interface

Summary:   The TRF3520 is single chip RF modulator/amplifier suitable for 900 MHz GSM applications. It combines a direct conversion I/Q modulator, a SSB mixer, an RF filter, a power amplifier driver, a buffered VCO, and a serial interface. During idle operation, the individual functional elements may be selectively placed in standby mode for minimum power consumption.
