† All typical values are at VCC = 5 V, VBB = –5 V, and TA = 25°C.
‡ This parameter is achieved through use of patented circuitry and is not recommended for applications in which the composite signals on the
transmit side are below – 55 dBm0.
NOTE 5: Measured by extrapolation from the distortion test result.
