NASA Team Develops New Ka-Band Communications System To Break Through The Noise
2015-02-20 02:33:30| rfglobalnet Home Page
The radio frequency band that many NASA missions use to communicate with spacecraft — S-band — is getting a bit crowded and noisy, and likely to get more jammed as science missions demand higher and higher data rates.

Norsat Ships Prototype Of ATOM 25 Watt Ka-Band Block Upconverter To Customer
2015-02-12 03:19:48| rfglobalnet Home Page
Norsat International Inc. ("Norsat") (TSX: NII and NYSE MKT: NSAT), a leading provider of innovative communication solutions that enable the transmission of data, audio and video for remote and challenging applications, today announced that it has shipped the first customer prototype of its upcoming ATOM 25 Watt Ka-band Block Upconverter (BUC). Ka-band communications offer higher throughput than Ku-band. The ATOM Ka-band BUC covers both commercial and military Ka-band (29-31 GHz).
TWT Amplifier: Ka-band dB-3840
2015-02-10 10:38:15| rfglobalnet Home Page
The dB-3840 is a TWT Amplifier (TWTA) operating in the frequency range of 34.5 to 35.5 GHz providing 700 Watts minimum peak output power at a duty cycle of up to 10%. A wideband, periodic permanent magnet (PPM)-focused, conduction-cooled TWT is used for power amplification. The power supply topology uses proprietary low-noise, high-efficiency designs to operate the RF signal path. An embedded micro-controller provides the interface, control and protection functions and status indication for the TWT Amplifier. Standard interface protocol for remote operation is RS-485. Other protocols such as RS-232, RS-422, Ethernet, or custom interfaces are available as options. The TWT Amplifier is encased in an environmentally sealed package for outdoor and antenna pedestal mounted applications, and uses integral forced-air cooling for thermal management.
