20 GHz Traveling Wave Amplifiers
20 GHz Traveling Wave Amplifiers
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.
- Boost fast signals
- Flat response in both amplitude and phase
- Easy to use, easy to cascade, compact See All Features
Features
Connect Directly to High Speed Photodetectors
The Model 1421 and 1422 Broadband Amplifiers are housed in a compact unit whose input and output connectors are Wiltron K-connectors. A female connector is used on the input to mate with the male connector used on the output of New Focus’ High-speed Photodetectors. In addition, there is a captive screw piercing the unit that allows the amplifier to be fastened to any Model 10XX or 14XX Series photodetector module.
Invert or Amplify Fast Signals
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.
Response of the Model 1421 to a 125-mV, 50-ps, positive step-function input. Response of the Model 1422 to a 125-mV, 50-ps, positive step-function input.
Flat Frequency Response
These traveling wave amplifiers offer a flat frequency response in both amplitude and phase.
