GENERAL SPECIFICATION

All the provided values are specified over the operational conditions (VDD and temperature) according to the

Receiver

in the bands: 30MHz - 2000MHz and 3000MHz - 12.75GHz. All specification below are measured at the antenna

port. The loss between IC inputs and the port is approximately 2dB

1) Sensitivity at chip pins is -79.5 dBm.

2) Guarantied over process variation and full temperature range -40 to +85°C.

3) Without any exception.

RSSI Extraction

The RSSI extraction block allows to determine the Received Signal Strength. The indicator output is an 8-bit

word, indicating the signal strength in dBm

The RSSI value is stored in the RSSI register. The value is latched when the base-band sends the access code

recognition signal (BPKTCTL) and is kept unchanged until the next RX active slot. The register can be read by

the base-band at any time
