Description
RF Transmit Output 1
P1dB up to +15dBm @ 50? differential 3.5GHz. The 50? matching is in part by
the bond/package inductance and an external component (tbd).
RF Transmit Output 2
Complementary signal to RFTX1
Voltage Supply of Power Amplifier Driving Module
Voltage Supply of Power Amplifier Driving Module
Power Switch of Receive Path
High active, digital CMOS input levels
Digital Test Bus Input/Output Digital
DTB input/output signal for testing purposes, connection and direction is
configurable over SPI.
Ground Supply SPI Interface Pads and of Digital Circuit Modules
Voltage Supply of Digital Circuit Modules
Voltage Supply of Digital Base Band Interface Pads
SPI Enable Digital Input
The rising edge of SCL and a low SDE indicate the start of a data transmission to
the SPI slave
SPI Clock Digital Input
At every rising edge the SDI data is latched into the internal SPI register. SDO
data change also on the rising edge.
SPI Data Digital Input
Serial SPI data input stream is started with SDE and contain first an address
byte. Read in is MSB first. The MSB of the address byte is the R/W control bit.
After the address byte there follows a number of data bytes. The actual number
of data bytes depends on the address.
SPI Data Digital Output
