NOTE:
1. When the digital input mode is used, the lower limit of the ambient operating temperature is higher than –30 °C. Preliminary characterization
results suggest a limit of –20 °C. This does not apply if the analog input mode is used.

Description
Note 1.
Synthesizer ON.
Transmitter ON with 8 dBm driver.
Maximum gain.
Synthesizer ON.
Transmitter ON with –1.5 dBm driver.
Maximum gain.
Synthesizer ON. Receiver ON.
Receiver gain control by:
• TX/RX ⇒ internal AGC
• RXMGC ⇒ 3-wire bus programming
• FASTTXRXMGC ⇒ fast 3-wire bus
Only Synthesizer and Xtal oscillator ON
Calibrates cut-off frequency of Tx and Rx
filters internally. Automatic transition to
SLEEP mode upon completion.
Calibration to reduce transmitter carrier
leakage. Automatic transition to SLEEP
mode upon completion.
Calibrates internal VCO.
Resets IC into power-up state (SLEEP
mode and all registers at default values)
