讯泰微波（Hittite Microwave)公司成立于1985年，专业设计并生产射频、微波应用领域的模拟/数字IC, MIC集成模块（可覆盖DC110GHz频率范围）以及仪器设备。Hittite的RFIC/MMIC产品则利用MESFET、PHEMT、HBT设计，应用GaAsInGaP/GaAs、InP、SOI、SiGe半导体加工过程中。Hittite为满足特殊需要整合多种功能，同时提供高集成IC、MCM以及其它低集成混合电路。Hittite采用主流的半导体与封装技术、独特的数字/射频平衡综合技术，为客户提供经济实惠、操作便捷的产品。 The HMC546LP2(E) is a failsafe SPDT switch in a leadless DFN surface mount plastic package for use in transmit-receive, and LNA protection applications which require very low distortion and high power handling of up to 10 watts. The device can control signals from 200 - 2700 MHz* and is especially suited for WiMAX and WiBro repeaters, PMR and automotive telematic applications. The design provides exceptional P0.1 dB of +40 dBm and +65 dBm IIP3 on the Transmit (Tx) port. The failsafe topology allows the switch to provide a low loss path from RFC to Tx, when no DC power is available. Features• High Input P0.1 dB: +40 dBm Tx• Low Insertion Loss: 0.4 dB• High IIP3: +67 dBm• Positive Control: 0/+3V to 0/+8V• Failsafe Operation - Tx “On”   When UnpoweredTypical Applications• LNA Protection, WiMAX, WiBro• Cellular/PCS/3G, TD-SCDMA   Infrastructure• Private Mobile Radio &   Public Safety Handsets• Automotive TelematicsFunctional Diagram 深圳浩时健电子长期供应Hittite的放大器、衰减器、鉴相器、分频器、倍频器、混频器、调制器、模拟移相器、功率检测器、射频开关、压控振荡器VCO、PLOs和微波模块在通信及工业应用领域的突出表现，为客户在研发设计中提供更多的机会。每年，Hittite都不断的突破新技术壁垒，应用新技术开发生产大量的MMIC产品和测试仪器设备。 HMC546LP2HITTITELP2单刀双掷开关HMC547LP3HITTITELP3单刀双掷开关HMC607HITTITEChip单刀双掷开关HMC607G7HITTITEG7单刀双掷开关HMC646LP2HITTITELP2单刀双掷开关HMC849LP4CEHITTITELP4C单刀双掷开关HMC174MS8HITTITEMS8单刀双掷开关HMC224MS8HITTITEMS8单刀双掷开关HMC446HITTITESOT26单刀双掷开关
