Microwave Search Receivers
SMR-3822A Wideband Microwave Receiving System
 The SMR-3822A Receiver, a member of the SMR-3000 family of high-performance synthesized microwave receivers, covers 0.1 to 20 GHz. Frequency extension to millimeter wave frequencies is possible using a frequency extender. An internal Spectrum Display Generator (SDG) generates data that can be used to develop RF Sweep and IF Pan spectrum displays on a remote workstation or laptop. The receiver provides simultaneous wideband IF outputs at 1 GHz (500 MHz bandwidth) and 160 MHz (100 MHz bandwidth) in addition to a post filtered 160 MHz IF output. All IF outputs have a noninverted spectrum; in addition, there is operator selectable inversion of the IF up to 20 GHz tuned frequency. |
SMR-3822 General Purpose Search Receiver
 The SMR-3822 Receiver, a member of the SMR-3000 family of high-performance synthesized microwave receivers, tunes 0.5 to 20 GHz. or 0.5 to 40 GHz using an external frequency extender.An internal Spectrum Display Generator (SDG) develops data that creates RF Sweep and IF Pan spectrum displays on a remote workstation or laptop. Rear panel connectors provide simultaneous wideband IF outputs at 1 GHz (500 MHz bandwidth), 70 MHz (50 MHz bandwidth), and 160 MHz (100 MHz bandwidth) in addition to a post filtered 160 MHz IF output. Internally, the 160 MHz IF is demodulated and AM and FM video is made available at rear panel connectors. A log video output is developed from the 1 GHz IF and is also available at the rear panel. Options are available. See Spec Sheet fore more information. In addition to the 70 and 160 MHz IF outputs, the IFD-3822 has AM and FM video outputs. The output level of the AM/FM video is variable over a range of 10% to 100%. The absolute output level range for FM video is 0.1 to 1.0 Vpk-pk and AM video is 0.1 to 1 Vpk |

Contact factory for data sheet
 The SMR-3822C Receiver, a member of the SMR-3800 family of high-performance synthesized microwave receivers, covers 0.5 to 20 GHz. Continuous coverage to millimeter waves is available by connecting the Cobham's FE-3820 Frequency Extender. The receiver provides simultaneous wideband IF outputs at 1 GHz (500 MHz bandwidth), and 160 MHz (100 MHz bandwidth). All IF outputs have a noninverted spectrum; in addition, there is operator selectable inversion of the IF across the entire tuning range. The front panel control layout is the same as the SMR-3822.

TU-6401 VME Microwave Tuner
The TU-6401 Microwave Tuner is an ultra high performance wideband microwave tuner. The RF downconverter used in conjunction with the DDS-based direct synthesizer module creates a microwave tuner featuring low phase noise and extremely fast tuning speed. This technology uncouples tuning speed from phase noise. All of these features are compressed into a two slot 6U VME design.The TU-6401 is capable of tuning over the entire 0.5 to 18 GHz range providing both narrowband and wideband outputs. The simultaneous analog outputs of 100 MHz BW and 500 MHz BW are centered at 160 MHz and 1 GHz, respectively. The analog outputs are suitable for direct input into an external A/D converter for special signal processing, spectral analysis or pulse parameterization.
TU-6402 VME Microwave RF Converter
 The TU-6402 Microwave VME RF Converter is the companion unit to the TU-6401 Microwave VME Tuner in a multi-channel system. LO’s are provided by the TU-6401 Tuner and can be daisy-chained to additional TU-6402 RF Converter modules. The TU-6402 is capable of tuning over the entire 0.5 to 18 GHz range providing both narrowband and wideband IF outputs. The simultaneous analog outputs of 100 MHz BW and 500 MHz BW are centered at 160 MHz and 1 GHz, respectively. The analog outputs are suitable for direct input into an external A/D converter for special signal processing, spectral analysis or pulse parameterization. |
SMR-4820 Advanced COMINT Search Receiver
 The SMR-4820 Microwave Receiver is designed for applications requiring portability and mobility. Through innovative design techniques and state-of-the-art microelectronics packaging, the SMR-4820 Receiver provides performance that was previously available only in larger receivers requiring greater power consumption. With integrated LO phase noise of less than 0.3 degrees rms and low group delay, the SMR-4820 is optimized for reception of digitally modulated and multichannel FDM and PCM signals. Wideband (unfiltered) and narrowband (filtered) IF outputs are provided. The wideband output has fixed gain and is selectable between 70 MHz and 140 MHz. The narrowband IF output provides 70 dB of gain control, AGC or MGC, and selectable IF bandwidths that cover a range of 10 to 55 MHz centered at 70 MHz. When the 140 MHz IF output mode is selected, gain controlled 140 MHz IF output is provided with 85 MHz bandwidth. An integrated demodulator provides AM detection and FM demodulation when the IF output is set to 70 MHz. Hey Everyone, It is strange to know that a beam of light can produce energy waves sound waves and electromagnetic currents waves that can kill a person . The power of light and scaler waves are dangerous..
