1 / 5 page HIGH GAIN X-BAND MMIC AMPLIFIER Preliminary specifications subject to change without notice Filtronic Compound Semiconductors Ltd Tel: +44 (0) 1325 301111 Fax: +44 (0) 1325 306177 Email: sales@filcs.com Website: www.filtronic.com 1 FMA246 Preliminary Datasheet v3.0 FEATURES: • 8.0 – 14.0 GHz Operating Bandwidth • 2.5 dB Noise Figure • 30 dB Small-Signal Gain • 19 dm Output Power • +6V Single Bias Supply • Adjustable Operating Current • DC De-coupled Input and Output Ports GENERAL DESCRIPTION: The FMA246 is a 3-stage, reactively matched pHEMT high-gain MMIC amplifier designed for use over the 8 to 14 GHz bandwidth. The supply voltage can be varied from +3V to +6V if needed. Operating current can be adjusted using the source resistor ladders located along the bottom edge, by bonding a particular pad to ground. The amplifier is unconditionally stable over all load states (-45 to +85 °C), and conditionally stable if the input port is open- circuited. LAYOUT: TYPICAL APPLICATIONS: • Low noise front end amplifiers • General X-Band gain block ELECTRICAL SPECIFICATIONS1: Note: 1. TAmbient = 22°C; Continuous operation at IDSS is not recommended 2. 60%IDSS is achieved by bonding pads "D", "G", and "K" (shown on page 2) to ground to drive the 1st, 2nd and 3rd stage amplifiers at 50%IDSS, 50%IDSS, and 75%IDSS respectively.
