Photodetectors for analog applications

The small size, light weight and low cost are main advantages of analog fiber links over coax links. In particular, analog fiber link is examined for photonic antenna (see Fig. 1) operating at high center frequencies in which a high power photodiode is deployed close to the antenna for downlink broadcasting [1]. High power and high output third order intercept point (OIP3) are among critical photodiode requirements in such application.
