AC ELECTRICAL CHARACTERISTICS (Demodulator LO = 965MHz) (continued)
(Typical Application Circuit when operated as a demodulator. I/Q outputs are recombined using network shown in Figure 5. Losses of
combining network not included in measurements. RF and LO ports are driven from 50 Ω sources. Typical values are for T A = +25°C,
V CC = 5.0V, I/Q DC voltage return = 0V, P RF = 0dBm, P LO = 0dBm, f RF = 780MHz, f LO = 965MHz, f IF = 185MHz, unless otherwise noted.)

Recommended functional range. Not production tested. Operation outside this range is possible, but with degraded
performance of some parameters.
Guaranteed by design and characterization.
Parameter also applies to demodulator topology.
Single-carrier WCDMA with 10.5dB peak-to-average ratio at 0.1% complementary cumulative distribution function,
P RF = -10dBm (P RF is chosen to give -65dBc ACLR).
No baseband drive input. Measured with the inputs terminated in 50 Ω . At low output levels, the output noise is thermal.
Note 10: The output noise versus P OUT curve has the slope of LO noise (Ln dBc/Hz) due to reciprocal mixing.
Note 11: Conversion loss is measured from the single-ended RF input to single-ended combined baseband output.
Note 12: The LO noise (L = 10 (Ln/10) ), determined from the modulator measurements can be used to deduce the noise figure
under-blocking at operating temperature (Tp in Kelvin), F BLOCK = 1 + (Lcn - 1) Tp / To + LP BLOCK / (1000kTo), where
To = 290K, P BLOCK in mW, k is Boltzmann’s constant = 1.381 x 10 (-23) J/K, and Lcn = 10 (Lc/10) , Lc is the conversion loss.
Noise figure under-blocking in dB is NF BLOCK = 10 x log (F BLOCK ). Refer to Application Note 3632: Wideband LO Noise in
Passive Transmit-Receive Mixer ICs.
