High-Dynamic-Range, Direct Up-/Downconversion
1500MHz to 2300MHz Quadrature Mod/Demod
Note 1: TC is the temperature on the exposed paddle.
Note 2: Guaranteed by production test.
Note 3: VI/Q = 2.66VP-P differential CW input.
Note 4: No baseband drive input. Measured with the baseband inputs terminated in 50Ω. At low output power levels, the output
noise density is equal to the thermal noise floor. See Output Noise Density vs. Output Power plots in Typical Operating
Characteristics.
Note 5: The output noise vs. POUT curve has the slope of LO noise (Ln dBc/Hz) due to reciprocal mixing. Measured at 10MHz offset
from carrier.
Note 6: 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), fBLOCK = 1 + (LCN - 1) TP / TO + LPBLOCK / (1000kTO), where TO = 290K,
PBLOCK 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
underblocking in dB is NFBLOCK = 10 x log (fBLOCK). Refer to Application Note 3632.
