5GHz, 5-Channel MIMO Receiver
AC ELECTRICAL CHARACTERISTICS—Tx MODE
(Operating conditions unless otherwise specified: V CC = 2.7V to 3.6V, T A = -25 N C to +85 N C, RF freq = 5.351GHz, LO freq = 5.35GHz.
Reference freq = 40MHz, ENABLE = high, CS = high, SCLK = DIN = low, with power matching at TXRF+ and TXRF- differential ports
using the Typical Operating Circuit ; 100mV RMS sine and cosine signal applied to I/Q baseband inputs of transmitter (differential
DC-coupled). Typical values measured at V CC = 2.85V, T A = +25 N C, channel bandwidths of 40MHz.) (Note 1)
