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 HMC641LC4 is a broadband non-reflective GaAs PHEMT SP4T switch in a compact 4x4 mm ceramic package. Covering DC to 20 GHz, this switch offers high isolation, low insertion loss and on-chip termination of isolated ports. This switch also includes an on board binary decoder circuit which reduces the number of required logic control lines from four to two. The HMC641LC4 is controlled with 0/ -5V logic, exhibits fast switching speed and consumes much less DC current than pin diode based solutions. The HMC641LC4 is also available in die form as the HMC641 Features• Broadband Performance: DC - 20 GHz• High Isolation: 42 dB @ 12 GHz• Low Insertion Loss: 2.1 dB @ 12 GHz• Integrated 2:4 TTL Decoder• 24 Lead 4x4mm SMT Package: 16mm²Typical Applications• Telecom Infrastructure• Microwave Radio & VSAT• Military & Space Hybrids• Test Instrumentation• SATCOM & SensorsFunctional 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: HMC245QS16HITTITEQS16开关HMC252QS24HITTITEQS24开关HMC253LC4HITTITELC4开关HMC253QS24HITTITEQS24开关HMC321LP4HITTITELP4开关HMC322HITTITEChip开关HMC322LP4HITTITELP4开关HMC344HITTITEChip开关HMC344LC3HITTITELC3开关HMC344LH5HITTITELH5 Hermetic开关HMC344LP3HITTITELP3开关HMC345LP3HITTITELP3开关HMC641HITTITEChip开关HMC641LC4HITTITELC4开关
