Product Description SXA Series Stanford Microdevices’ SXA Series are high performance GaAs Heterojunction Bipolar Transistor (HBT) MMICs housed in thermally-efficient plastic packages. These GaAs HBT MMICs are fabricated using molecular beam epitaxial growth technology for consistent and repeatable performance from wafer to wafer and lot to lot. DC-2.5 GHz MMIC Amplifier Scheduled for Mar-98 Release Product Features • High Reliability 2.0 micron HBT Technology • High P1dB : +21dBm to +27dBm • High 3rd Order Intercept : +39dBm to +43dBm • Surface-Mountable Plastic Package • Broadband Performance These amplifiers utilize Darlington pair topology for broadband performance from DC-2.5 GHz. Heterojunction technology minimizes emitter non-linearities resulting in high TOIP to P1dB spreads, ideal for high-linearity applications. Also available in die form, these devices are fully passivated for ruggedness and durability. Both bond pad and backside metal are Au-metallized for compatability with automatic and manual die attach and bonding equipment. Applications • High Linearity Applications • Wireless LAN, WAN Electrical Specifications at Ta = 25C Symbol Parameters: Test Conditions: Z0 = 50 Ohms Technology Units Min.
