description  
The TRF1500 is a dual-band/dual-mode personal communications system (PCS) receiver for cellular  
telephones operating dual mode (analog and digital) in the 800-MHz band and single mode (digital) in the  
1900-MHz band. The TRF1500 consists of a low-noise amplifier (LNA) and mixer for each band. The high band  
uses an image rejection mixer for down conversion while the low band relies on an off-chip image rejection filter  
between the LNA and mixer.  
The local oscillator (LO) inputs additionally have buffered outputs that can be used in either single-ended or  
differential mode for a phase-locked-loop (PLL) configuration. A state is also available that allows the low-band  
LO to serve as the high-band LO through a mode-selectable frequency doubler.  
A wideband mixer is also available for transmit loop architectures commonly used in advanced mobile phone  
systems, global systems for mobile communications, and digital cellular systems.  
Power consumption is low and can be further reduced by operating the TRF1500 in sleep mode. Typical power  
consumption for each receiver function is shown in Table 1.  
The TRF1500 is available in a 48-pin plastic thin-quad flatpack package (TQFP) and is characterized for  
operation from –30 C to 85 C operating free-air temperature.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
