Description

845-26 100kHz – 26 GHz Microwave Signal Generator

845-26 / Model 845 RF Microwave Signal Generator is a low-noise and fast-switching microwave signal generator covering a frequency range from 9 kHz up to 26.5 GHz. The Model 845 Microwave RF Signal Generator offers a wide and accurately-levelled output power range with high spurious suppression. Advanced frequency synthesis with fractional-N divider makes for low SSB phase noise and micro-Hz frequency resolution.

The Model 845 is now available in 12, 20, & 26.5 GHz frequencies. In addition, the Model 845 can be customized and configured to each user’s specific needs. Available with HP (high output power), LO (CW only, no modulation – only available on 20 GHz & 26.5 GHz), & R (1U rack mountable configuration).

RICH SET OF FEATURES IN THE MODEL 845 SERIES

The Model 845 Microwave RF Signal Generator also includes AM, DC-coupled, low distortion wideband-FM, PM, FSK and PSK, frequency chirp, and fast pulse modulation with an internal pulse train generator as standard. Three internal modulation sources are available, and all modulation modes can be combined. This allows the generation of complex modulation signals for modern communication and location systems.

The Model 845 is ideally suited for applications where a high-quality CW microwave source with analog modulation is required. The Model 845 operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) and can be phase-locked to any external reference from 1 to 250 MHz. Additionally, the combination of pulse modulation and FM simulates Doppler effects or chirp signals. Simultaneous AM and pulse modulation provide the types of signals occurring in pulse radar applications with a rotating antenna. What’s more, the combination of FM and AM can be used to check the fading effects of FM receivers.

The Model 845 operates on line or battery power making it useful for field applications or large laboratories. Although the Model 845 Microwave / RF Signal Generator introduces the smallest footprint in its class, it clearly can fill the largest shoes!
