LX5537 ® TM InGaP HBT 2.3 – 2.7 GHz Power Amplifier P RODUCTION D ATA S HEET KEY FEATURES DESCRIPTION Advanced InGaP HBT 2.3-2.7GHz Operation Single-Polarity 3-4.2V Supply Power Gain ~ 31 dB or higher 23.5 dBm @2.5% EVM /3.6V 25 dBm @2.5% EVM /4.2V 24.5 dBm @4% EVM /3.6V 26 dBm @4% EVM /4.2V 22% Efficiency @24.5dBm/3.6V Optional 26dB Attenuation Complete On-Chip Input Match Simple Output Match for Optimal EVM Temperature-Compensated On-Chip Output Power Detector with Wide Dynamic Range Small Footprint: 3x3mm2 Low Profile: 0.9mm LX5537 also features an on-chip power detector at the output port of the PA to help reduce BOM cost and PCB space for implementation of power control in a typical wireless system. The 26dB attenuation function can optionally be used to reach low gain mode. The LX5537 is available in a 16pin 3mm x 3mm quad flat no lead package (QFN 3×3-16L). The compact footprint, low profile, and excellent thermal capability make the LX5537 an ideal solution for WiMAX/WiBro as well as 802.11b/g/n applications. IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com WWW . Microsemi .C OM The LX5537 is a power amplifier optimized for 802.16e(WiMAX/WiBro) and 802.11b/g/n applications in the 2.32.7 GHz frequency range. The PA is implemented as a three-stage monolithic microwave integrated circuit (MMIC) with active bias, on-chip input matching and output pre-matching. The device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process (MOCVD). It operates with a single positive voltage supply of 3-4.2V, and provides power gain of 31dB and output powers of +23.5dBm at 3.6V and +25 dBm at 4.2V for 2.5% EVM in the 2.52.7GHz.
