AC ELECTRICAL CHARACTERISTICS—Rx MODE (continued)
(Operating conditions, unless otherwise specified: V
= 5.35GHz. Reference frequency = 40MHz, ENABLE = high, CS = high, SCLK = DIN = low, with power matching at RXRF+ and
RXRF- differential ports using the Typical Operating Circuit. Receiver I/Q output at 100mV
resistance and 10pF load capacitance. The RSSI pin is loaded with 10kI load resistance to ground. Typical values measured at V
= 2.85V, channel bandwidths of 40MHz, T
