Amplifiers Span 20 To 4000 MHz

Feb. 13, 2008

To satisfy applications ranging from point-topoint and multipoint radios to military jammers, an amplifier line boasts noise figures down to 0.9 dB. The QBH-8900 series amplifiers are available in frequencies from 20 to 4000 MHz. Second-intercept-point values range up to +75 dBm while intercepts reach +45 dBm. The QBH-8900 series from 10 to 28 dB. In addition to a lightweight, low-cost, package, no external circuitry is needed. The amplifiers, which feature internal blocking caps, biasing circuitry, and RF matching, require only a direct-current (DC) power supply. P&A: $50 to $99 depending on quantity and configuration, 4 to 6 wks.
