RLC电子公司宣布开发出设计工作频率为DC～18GHz的PA系列二进制程控步进衰减器。两种基础型号为PA124和PA125的衰减器的衰减范围分别为0—15dB。步进1dB和0—70dB、步进10dB。其控制为标准的二进制格式。这些衰减器可以不间断或闭锁工作,采用12V或28V线圈和选择晶体管一晶体管逻辑(TTL)驱动器。上述衰减器的电压驻波比(VSWR)优于1.9,视子频带而定;25℃下平均功率2W,阻抗50Ω,最大开关速度15mS。
RLC Electronics Corporation announced the PA series of binary programmable step attenuators designed to operate at DC ~ 18GHz. Attenuation ranges for the two attenuators of the base models PA124 and PA125 are 0-15dB respectively. Stepping 1dB and 0-70dB, stepping 10dB. Its control is standard binary format. These attenuators can work uninterrupted or latched, using 12 V or 28 V coils and select transistor-transistor logic (TTL) drivers. The VSWR of the above attenuator is better than 1.9, depending on the subband frequency. The average power at 25 ° C is 2W, the impedance is 50Ω, and the maximum switching speed is 15mS.
