Multiformat signal generator supporting up, down and dual-chirped, polyphase-coded and amplitude-shift keying (ASK) signals for multichannel transmission with multioctave tuning and dispersion immunity.

3 – 42 GHz (extendable)

Single sideband-equivalent modulation eliminates dispersion-induced power fading. An active demultiplexer based on optical injection locking to select individual comb lines from the optical frequency comb (OFC enables ultra-wideband (UWB) frequency tuning without the need for a widely tunable RF.

Multifunctional RF, 5G/6G radio-over-fiber, and distributed radar systems

500 MHz bandwidth, 1 µs duration for a single-chirp 6 GHz f0; 1 GHz bandwidth for dual-chirp. 0.2 Gb/s at 3 GHz f0, 0.5 Gb/s at 6 GHz f0 for an ASK-coded signal. 0.2 Gb/s at 3 GHz f0, 0.5 Gb/s at 6 GHz f0 for a quadri-phase coded signal
