APD module

C5658

Detects optical signals at 1 GHz, with high sensitivity

APD module C5658 is a highly sensitive photodetector consisting of a Si APD (avalanche photodiode), a bias power supply and a low-noise
amplifier, all integrated into a compact case. The APD used has an effective active area of φ0.5 mm to allow efficient coupling to a light beam in
applications such as spatial light transmission. The APD internally multiplies the photocurrent to produce an ample gain (set to 100 times for
C5658) and also features high-speed response, achieving detection limits up to 1 GHz wideband and -48 dBm (16 nWr.m.s.) noise level in
combination with the low-noise amplifier. C5658 also incorporates a thermosensor and a temperature-compensated bias power supply necessary
for stable operation of the APD. Highly sensitive optical measurements can be made just by supplying +12 V to C5658.

* VSWR (Voltage Standing Wave Ratio)
If internal matching of elements on a signal transmission line (matching between element input/output impedance and signal line
impedance) is poor, signal reflections occur that generate standing waves on the signal line. The VSWR is the ratio of standing
wave maximum amplitude (V Max.) to minimum amplitude (V Min.) and indicates how well the impedance is internally matched.
When this internal matching is complete, no standing waves exit and the VSWR is 0 (zero).
