20-GHz Amplifiers

• Boost fast signals

• Flat response in both amplitude and phase

• Easy to use, easy to cascade, compact

In some cases, amplifying your photodetector's output is essential—especially when you're using low-sensitivity instruments such as spectrum analyzers, frequency counters, or oscilloscopes. That's why we designed these high-performance traveling-wave amplifiers (TWAs) to boost the signals from our high-speed photodetectors. They can also be used as general-purpose microwave amplifiers.

The double-shielded cases are designed to connect directly to our photodetector modules, reducing standing-wave effects and RF pick-up at the input. The 8.5-dB-gain Model 1421 inverts your signal, while the 18-dB-gain Model 1422 does not. The standard version comes with a low-frequency cutoff of 50 MHz. Specify the "-LF" option for a low-frequency cutoff of 14 MHz. Power cables are provided.

We strongly recommend our Model 0901 power supply (page 138) for use with these amplifiers.
