FUNCTIONAL DESCRIPTION
The SA2421 is a 2.45 GHz transceiver front-end available in the
TSSOP-24 package. This integrated circuit (IC) consists of a low
noise amplifier (LNA) and up- and down-converters. There is an
enable/disable switch available to power up/down the entire chip in
1
μ
s, typically. This transceiver has several unique features.
The LNA has two operating modes: 1) high gain mode with a gain =
+14.3 dB; and 2) low gain mode with a gain –19 dB. The switch for
this option is internal and is controlled externally by high and low
logic to the pin. When the LNA is switched into the attenuation
mode, active matching circuitry (on-chip) is switched in (reducing the
number of off-chip components required). To reduce power
consumption when the chip is transmitting, the LNA is automatically
switched into a “sleep” mode (internally) without the use of external
circuitry.
