Technical content

The VPDV2120 is a very compact, hermetically packaged, optical detector module with an ultra-high RF output power of >22 dBm at a frequency of 10 GHz. It offers a high responsivity of 0.55 A/W (1550 nm) and a very high saturation photocurrent of 120 mA at 10 GHz. The device exhibits a high linearity, with typical OIP3 values above 30 dBm at a frequency of 10 GHz and does not require any cooling. The device is using a modified uni-travelling carrier (MUTC) photodetector chip. The VPDV2120 is not matched to 50 Ω. For applying a bias voltage of -6 V, an external Bias-Tee is required.
