HMC470 DC5V 3GHz 1dB to 31dB 5-bit GaAs IC Digital Radio Frequency Attenuator Module

Description HMC470 is a wideband 5 bit GaAs IC digital attenuator in a low cost leadless surface mount package This digital attenuator for each single positive voltage control circuit uses off chip AC grounded capacitors and works near DC This feature makes it very suitable for various RF and IF applications Operating at frequencies from DC to 3 GHz the insertion loss is less than 1 5 dB typical For a total attenuation of 31 dB the attenuator bit values ​​are 1 LSB 8 2 4 and 16 dB The attenuation accuracy is very high the typical step size error is ±0 3 dB and the IIP3 is 45 dBm Five TTL CMOS control inputs are used to select each attenuation state Need 5V Vdd single bias Features ●1 dB LSB step to 31 dB●Each individual control line●TTL CMOS compatible control●Step error ±0 3 dB typical value ● 5V single power supply●16 pin 3x3mm QFN package 9 mm2Application ●Cellular UMTS 3G infrastructure●ISM MMDS WLAN WiMAX●Microwave radio and VSAT●Test equipment and sensorsSpecification Supply voltage maximum voltage 7VMaximum input power 27dBmControl voltage range V1 V5 1V Vdd 1VTest parameters vector scanning power 0dBm Insertion loss no attenuation V1 V5 11111 Product size 50 x 50 x 9mmProduct weight 20gPackage included 1 x HMC470 5 bit GaAs IC digital attenuator
