Ultra-Broadband Pick-off Tee
PSPL5370 Datasheet
The PSPL5370 Pickoff Tee is an ultra-broadband resistive coupler,
which provides a scaled (5x or 10x) replica of signals passing
through the tee. The device exhibits excellent through-line insertion
loss and pickoff ratio stability for frequencies from DC to >25 GHz.
The PSPL5370 features good impedance match acros s a w i de
range of frequencies, with return loss typically >15 dB from 0-25
GHz.
■ Low insertion loss
■ DC to >25 GHz
■ 5x and 10x pickoffs
■ ≤14 ps risetime
