3.4.1
Low Noise Amplifier (LNA)
The LNA is an on-chip cascode amplifier with a voltage gain of 15 to 20dB. The
gain figure is determined by the external matching networks situated ahead of
LNA and between the LNA output
LNO
(Pin 6) and the Mixer Inputs
MI
and
MIX
(Pins 8 and 9). The noise figure of the LNA is approximately 2dB, the current
consumption is 500μA. The gain can be reduced by approximately 18dB. The
switching point of this AGC action can be determined externally by applying a
threshold voltage at the
THRES
pin (Pin 23). This voltage is compared internally
with the received signal (RSSI) level generated by the limiter circuitry. In case
that the RSSI level is higher than the threshold voltage the LNA gain is reduced
and vice versa. The threshold voltage can be generated by attaching a voltage
divider between the
3VOUT
pin (Pin 24) which provides a temperature stable
3V output generated from the internal bandgap voltage and the
THRES
pin as
described in Section 4.1. The time constant of the AGC action can be deter-
mined by connecting a capacitor to the
TAGC
pin (Pin 4) and should be chosen
along with the appropriate threshold voltage according to the intended operat-
