... Chebyshev frequency response. Most differential ampli- fi ers require many precision external components to tail or gain and bandwidth. In contrast, with the LT6600-2.5, two external resistors program differential gain, and the Output fi lter’s 2.5MHz cutoff frequency and passband ripple are RMS internally set ...

... LT6600-2.5 will have lower distortion with larger load resistance yet the analyzer input is typically 50Ω. The 4:1 turns (16:1 impedance) transformer and the two 402Ω resistors of Figure 5, present the output of the LT6600-2.5 with a 1600Ω differential load, or the equivalent of 800Ω to ground at each output. The impedance seen by the network analyzer input is still 50Ω ...

... There is a need to ensure that the die’s junction temperature does not exceed 150°C. The LT6600-2.5 S8 package has Pin 6 fused to the lead frame to enhance thermal conduction when connect- ing to a ground plane or a large metal trace. Metal trace and plated through-holes can be used to spread the heat generated by the device to the backside of the PC board ...
