Simply configured Radio on Fiber link yielding positive gain for mobile phone system

Abstract

This paper proposes a simple and cost-effective configuration for an analogue Radio on Fiber (RoF) link without any amplifier comprising driver and receiver circuits with stubbed microstrip lines. This simple configuration yields a gain of +4 dB with a spurious free dynamic range (SFDR) of 58 dB. An adjacent carrier leakage ratio (ACLR) of less than −63 dB and an error vector magnitude (EVM) of less than 1% are also achieved. These results satisfy the specifications given in the technical standard published by the third generation partnership (3GPP).
