A transceiver for a phased array antenna comprises a laser light source arranged to provide an optical spectrum comprising a plurality of spaced wavelengths. The transceiver further comprises a dispersion unit arranged to introduce a delay to a plurality of spectral components of the optical spectrum associated with the spaced wavelengths. The delay is dependent on the wavelength of the spectral components of the optical spectrum. The transceiver further comprises a first optical filter configured to select a plurality of spectral components received from the dispersion unit. The transceiver further comprises a first heterodyning device configured to generate a signal for transmission by the phased array antenna by heterodyning the selected spectral components associated with different ones of the spaced wavelengths of the laser light source. The transceiver is configured to receive signals from the phased array antenna. The transceiver further comprises a modulator configured to modulate spaced wavelengths from the said laser light source with the received signals. The spaced wavelengths are associated with the spectral components used to generate the signal for transmission. The transceiver further comprises a second heterodyning device configured to heterodyne spectral components associated with different ones of the spaced wavelengths of the laser light source.
