AR Worldwide Modular RF has designed and built a custom amplifier module for the emerging wireless access market. The model CMS1070 was created in 45 days to meet a client's selected frequency band and a very demanding linearity specification.
The CMS1070 is a 3.4 to 3.7 GHz solid-state power amplifier module for the wireless broadband network. This 20 W, 43 dBm output linear power amplifier has a scaleable gain of 20 to 50 dB and is designed to meet the WiMAX 802.16d specifications. It can be modified to meet various types of OFDM or NPR requirements. The module comprises a printed wiring assembly housed in a machined aluminum enclosure. The amplifier is protected from thermal overload, over power, over voltage or wrong voltage polarity as well as having an internal isolator.
