Upconverter/Downconverter
*NEW* Baseband Converter brochure
 Sage Laboratories produces a wide range of narrowband and broadband upconverters and downconverters for EW applications. These converters utilize Sage's mixers integrated with other necessary functional blocks such as limiters, filters, switches and amplifiers. These units are usually custom designed to a specific customer requirement.
An example of a specification for a narrowband downconverter assembly utilizing image rejection mixers for use in airborne radar receivers is:
| Frequency Range |
10% BW in X-Band |
| IF |
55 - 65 MHz |
| Gain, RF to IF |
40 dB |
| Amplitude Match |
0.3 dB |
| Phase Match |
±4 ° |
| Noise Figure |
3.5 dB maximum |
| Dynamic Range |
70 dB |
| Output 1 dB Compression Point |
15 dBm |
| Switching Speed |
20 ns |
| Isolation |
60 dB |
| LO Input Powe |
5 to 8 dBm |
