Nominal performance, as noted in the following tables, while not warranted, provides information useful in applying the device.
1. An LO power of between 14.5 to 16 dBm at the mixer’s LO input is necessary to achieve the given frequency response and spectrum analyzer amplitude
accuracy specifications. When LO power varies between 14 to 18 dBm at the mixer’s LO input, add ±1 dB to the frequency response and spectrum analyzer
amplitude accuracy specification.
