... Chebyshev frequency response. Most differential amplifi- ers require many precision external components to tailor gain and bandwidth. In contrast, with the LT6600-10, two external resistors program differential gain, and the filter’s Output 10MHz cutoff frequency and passband ripple are internally P-P set ...

... Similarly, the output the LT6600-10 will have lower distortion with larger load resistance yet the analyzer input is typically 50 . The 4:1 turns (16:1 impedance) transformer and the two 402 resistors of Figure 5, present the output of the LT6600-10 with a 1600 differential load, or the equivalent of 800 + IN to ground at each output ...

... Noise The noise performance of the LT6600-10 can be evaluated with the circuit of Figure 7. Given the low noise output of the LT6600-10 and the 6dB attenuation of the transformer coupling network, it will be necessary to measure the noise floor of the spectrum analyzer and subtract the instrument noise from the filter noise measurement ...
