We report InP/InGaAs modified unitraveling-copyright balanced photodiodes (PDs). The back-illuminated PDs were flip-chip bonded on diamond submounts for enhanced heat sinking. The device demonstrated a 3-dB bandwidth of 8 GHz and a 30-dB common-mode rejection ratio at frequencies of <; 10 GHz. https://lockdownsecuritycanada.shop/product-category/anti-rodent-tape/
