MAX2837
2.3GHz to 2.7GHz Wireless
Broadband RF Transceiver
AC Electrical Characteristics—Rx MODE (continued)
(MAX2837 evaluation kit: VCC_ = 2.8V, fRF = 2.502GHz, fLO = 2.5GHz; receiver baseband I/Q outputs at 90mVRMS (-21dBV), fREF
= 40MHz, ENABLE = RXENABLE = CS = high, TXENABLE = SCLK = DIN = low, with power matching for the differential RF pins
using the typical applications and registers set to default settings and corresponding test mode, TA = +25°C, unless otherwise noted.
Lowpass filter is set to 10MHz RF channel BW. Unmodulated single-tone RF input signal is used, unless otherwise indicated.) (Note 1)
