5.5 Electrical Characteristics

at TA = 25°C, VCC_PA = 3.3V, VCC = 3.3V, f = 915MHz, shorted RX_FLT and LNA_IN pins, shorted TX_FLT and PA_IN pins,

RF transmit specifications from TR to ANT pin, RF receive specifications from ANT to TR pin, 50Ω source and load at input

and output RF pins, respectively; measured on EVM and de-embedded up to the device pins (unless otherwise noted)
