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 wh.
-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.
