Whats the best way to go about measuring the bandwidth?
You can either measure the frequency response on the oscilloscope by sending in a range of frequencies and noting the resulting magnitude,or you can use the ESA-L1500A Spectrum Analyzer, located next to theVNA closest to the TA desk. This spectrum analyzer allows you to send in a test RF signal of a given power and then find the output power from your filter. • For your TX IF, since you won’t have any gain, put in 0 dBmfor the “Source Amplitude.” Your output should come out to be around-3 dBm (since maximum power transfer is 1/2 for matched impedances). • For your RX IF, you should test with a -58 dBm signal (the lowest this will go to), since you will probably have a gain close to +60 dB. If you have a 3 kΩ resistor on the output (to prevent thespectrum analyzer from loading the op-amp, which has a low-impedanceoutput), you will attenuate -35 dB from the 3kΩ-50Ω voltagedivider going in to the spectrum analyzer; just add 35 dB to your gainto get a rough estimate of the actual gain of y
