with Limiter and RSSI
____________________________Typical Operating Characteristics (continued)
(MAX2511 test fixture, VCC = +3.0V, 0.01µF across CZ and CZ, MIXOUT tied to VREF through 165Ω resistor, TXIN, TXIN tied to
VREF through 50Ω resistor, TXOUT and TXOUT loaded with 100Ω differential, GC open, LIMOUT, LIMOUT loaded with 2kΩ differ-
ential, TANK and TANK driven with -2.5dBm from a 100Ω source; OSCOUT AC-terminated with 50Ω, 100pF at RSSI pin, 0.1µF at
VREF pin, Rx inputs and Tx outputs differentially coupled, PRXIN, RXIN = -28dBm (200Ω system), fRXIN, RXIN = 425MHz, fLO = 435.7MHz,
fTXIN, TXIN = 10.7MHz, TA = +25°C, unless otherwise noted.)
