| MODULE 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 0.5 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.

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). =800 nm High band Low band =800 nm 25 C 10 C Dark state s Signal connector Parameter Signal output Power supply connector Standard SMA D-sub 9 pin s General specifications Parameter Supply voltage Current consumption Dimensional outline Weight Condition Excluding projecting parts Value +12 0.1 100 28 x 50 x 60 120 Unit V mA mm g APD module s Pulse response waveform OUTPUT VOLTAGE (mV) 100 mV/div.
