Product details
The CPI LKR12S70 is a Ku-Band low noise amplifier (LNA) from CPI's LK-12000 Series. It covers 10.70–12.75 GHz (full Ku-band receive) with a maximum noise temperature of 70 K at +23 °C, guaranteed across the full band.
It provides 60 dB minimum gain (64 dB typical) with ±0.5 dB flatness across the band, a WR-75 waveguide input with input and output isolators, and an SMA output (Type N optional). DC can be fed up the RF output cable or through the MS power connector.
Order it as LKR12S70-XXXX: the suffix selects gain (60 or 50 dB), output power (+12 or +20 dBm), DC or AC power, and an SMA or Type N output. The LK-12000 Series comes in 4 listed models; compare them on the series page.
