(Reuters) -Filtronic's shares surged 50% to a decade-high on Wednesday after the British engineering group deepened its partnership with SpaceX's Starlink platform and gave the Elon Musk-controlled company the option to take a stake.

Filtronic, which manufactures products for the aerospace, defence, space and telecom infrastructure markets, already supplies Starlink with E-band solid state power amplifiers (SSPA), which are used for low-earth orbit satellites.
