Using advanced microstrip technology, ultra-small size
Attenuation values are adjustable in a power-on state, no
sudden big reflection.
It adopts an innovative technology, and thus it eliminates
sudden big reflection in attenuators when attenuation is
being adjusted, preventing the preliminary RF circuit from
being burnt, and keeping the system stable
Step values: 0.5 dB,1dB, 2dB, 4dB, 8dB,10dB
52 attenuation values
High attenuation accuracy, low insertion loss
High adjustment accuracy
Low cost – High Performance
Adjusting the transmitting (receiving) distance of RF
signal precisely. Adjusting accuracy is limited to 5cm.
Switch repeatability avg.> 10000 operations (5000 cycles)
per switch.
PC(Polycarbonate) Switch, operating temperature of
120℃ is available.
