Proprietary Information | www.apitech.com | micro.apitech.com | +1.888.553.7531 | MicrowaveSales@apitech.com Page # Rev Date: 800 to 2200 MHz Class A Linear Design Part Number: QB-840 1 Watt Broadband Driver Amplifier 5/12/2014 1 Features Notes: 1. Specification ratings are based on measurements in a 50 ohm system with a DC supply voltage tolerance of ± 2%. 2. With the RF output port terminated into 50 ohms (Load VSWR ≤ 2.0 :1) 3. Maximum Operating Case Temperature is defined as the baseplate temperature which, if exceeded for extended periods, could result in premature unit failure. This data is provided for user reliability information. This may or may not represent the maximum temperature for electrical parameter specifications.

Using a high reliability GaAs MESFET technology in a balanced configuration, the module is able to achieve 1W of output power at 1dB compression with exceptional linearity, gain flatness, and VSWR at the In/Out ports across the entire frequency range. The discrete design is supplied in an aluminum package with SMA-F connectors for the RF ports and a 9 pin D-Sub for DC power to facilitate system integration. Operating from a nominal +12V power supply, the QB-840 draws approximately 420 mA with a small signal gain of 11 dB and a typical noise figure of 6.5 dB. Optional services include over temperature testing, environmental screening, and(or) alternate package configurations. |
