1 Product Specification 58 Uplander Way Culver City, CA 93 Tel: (31) Miniature, Ruggedized, GHz RF over Fiber Transmitter PRODUCT FEATURES Bandwidth.5 to GHz (with LNA); DC to 3 GHz (no LNA) Reconfigurable with and without LNA Noise Figure < 8 db (< db no LNA) at 1 GHz Very High Linearity, High intrinsic RF Gain, High RF Saturation MIL-STD tested for temperature, shock, vibration, barometric pressure, EMI Compact size includes low noise electronics and all optical components APPLICATIONS Broad band RF over fiber 1 m to 1 km Antenna remoting for wireless systems, electronic sensors, and networks RF over fiber systems that require robust, ruggedized, compact solutions High frequency phase interferometry RF systems DESCRIPTION This module is a miniature, ruggedized GHz analog RF over Fiber (RFoF) optical transmitter which is part of a high performance solution for RF remoting. It is a self-contained, compact module that includes ultra-low noise driver electronics, low RIN laser with shot noise performance, high performance modulator, and optional LNA. The transmitter can be operated either by an on/off switch using predefined settings or through a built-in GUI that enables the user to control all internal components (i.e. laser, modulator, and LNA operating parameters). The transmitter offers 5 MHz- GHz RF instantaneous bandwidth which, when coupled with APIC s high responsivity and linearity receivers, offers unmatched RFoF link performance. For applications that require high sensitivity and very low minimum detection signal threshold, use of the optional LNA is recommended. For applications that require higher linearity, the no-lna option is recommended. ORDERING INFORMATION MicroATx--L-WL-FL-FC FC = Fiber connector type (APC = FC/APC is standard) FL = Fiber length (in meters; standard is 1±.5 m) WL = Wavelength in nm (1,53 1,55 nm on ITU 1 GHz grid) L = with LNA (standard); N = No LNA = DC to GHz instantaneous bandwidth
