SA1620BE規(guī)格書詳情
DESCRIPTION
The SA1620 is a combined receive (Rx) and transmit (Tx) front-end for GSM cellular telephones. The receive path contains two low noise amplifiers (LNA1 and LNA2) with four switchable attenuation steps. A Gilbert Cell mixer in the receive path down-converts the RF signal to a first IF of 70 to 500 MHz. A second Gilbert Cell in the transmit path transposes a GMSK or phase modulated IF to RF by image reject mixing and has a fixed IF of 400 MHz. A buffered LO signal is fed to Rx and Tx mixers. Rx or Tx path or the entire circuit may be powered-down.
FEATURES
?Excellent noise figure: <2dB for the LNAs at 950MHz
?LNAs matched to 50?with external matching components
?LNAs with gain control, 59dB dynamic range in four discrete step
?LNA gain stability ±0.5dB within -40 to 85°C
?Feedthrough attenuation LNA1 to Rx mixer ≥35dB
?Tx power adjustable from -3 to +12dBm by external resistor
?Direct supply: 2.7V to 5.5V
?Battery supply voltage VBATT= 3.3V to 7.5V or direct supply
?Two DC regulators programmable for 3.0V, 3.4V, 3.7V or 5.1V
?Low current consumption: 28mA for Rx or 59mA for Tx
?Fully compatible with SA1638 GSM IF Digital I/Q circuit
APPLICATIONS
?900MHz front end for GSM hand-held units
?Portable radio, TDMA systems
