Typical values are at VCC = +5V, fLO = 1850MHz, TC = +25°C, unless otherwise noted.)

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 50 Ω. 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. |
