Product details
The CPI LLB15S35 is a L-Band low noise amplifier (LNA) from CPI's LL-1500 Series. It covers 1510–1577 MHz with a maximum noise temperature of 35 K at +23 °C, guaranteed across the full band.
It uses a HEMT/MMIC design with an internal regulator, reverse polarity protection and a fault alarm, and provides 50 dB minimum gain (60 dB optional) with ±0.5 dB flatness. Connectors are SMA, and it runs on +11 to +15 VDC from -40 °C to +60 °C.
Order it as LLB15S35-XX: the suffix selects gain (50 dB standard or 60 dB) and output power (+10 or +20 dBm). The LL-1500 Series comes in 3 listed models; compare them on the series page.
