Products Information
Broad Band Direct Current Amplifier with Both Positive and Negative Output RoHS

Broad Band Amplifier T-WBA01Z
A compact but low-price Broad Band amplifier. Used as an amplifier for positioning before high-speed AD convertors etc., and thus of more than adequate bandwidth and gain. Supports 2 types of outputs: both positive and negative. Both match 50Ω, and hence capable of transmitting accurate waveforms. Very compact and light, and thus easily used anywhere.
