LNA RF Output. This is an open collector output that requires an external load to VCC. This pin requires matching for optimum gain 11 RLNI I (analog) Receive LNA RF input. This pin is directly connected to the base of an NPN transistor. The input to this pin should be AC coupled using an external capacitor. This input will require matching for optimum performance PA Section 3 TRFI I (analog) Transmit RF Power Amplifier (PA) input. Requires RF choke to VCC that can handle up to 150mA. The VCC end of the choke requires both RF and low frequency decoupling to ground to minimize supply modulation 9 TPS I (analog) This pin is the non-inverting input of an op amp. The voltage on this pin sets the RF power produced by the PA, permitting variable power operation under control of the baseband circuits (see Figure 2) 10 TPA I (analog) This pin is the inverting input of an operational amplifier. A resistor from this pin to GND scales the TPS input voltage control range to match that of the external baseband control circuits. If scaling of the TPS input range is not required the TPA pin can either be grounded or left floating (see Figure 2) 18 TRFO O (analog) Transmit RF Power Amplifier output. Open collector output. Requires RF choke to VCC that can handle up to 150mA. The VCC end of the choke requires both RF and low frequency decoupling to ground to minimize supply modulation Pin # Signal Name I/O Type Description |
