{"product_id":"cpi-lrk2","title":"CPI LRK2 1:2 Ku-Band Redundant LNA System, 10.70–12.75 GHz","description":"\u003cp\u003eThe CPI LRK2 is a 1:2 redundant LNA system from CPI's LRK-1000 Series for Ku-Band earth stations. It protects two receive chains, typically both polarizations of a dual-pol feed, with one shared spare LNA. If either online LNA fails, the indoor controller switches the spare into that chain automatically.\u003c\/p\u003e\u003cp\u003eThe plate carries CPI LK-12000 Series LNAs (65 to 90 K) on a WR-75 waveguide input, with options for a 13.75–14.50 GHz Tx reject filter, -40 dB input crossguide couplers, -20 dB output couplers and an offline I\/O port. The 1RU controller has dual power supplies and SNMP over Ethernet.\u003c\/p\u003e\u003cp\u003eOrder it as LRK2XXX-XXXXXXX; Digisat completes the order code from your band, LNA and option choices.
