  • Broadband Low Noise Amplifier 0.8dB NF 50MHz to 4GHz 18dB Gain with Bias Tee

    Part Number: LNA50M4GBT is a high-linearity, ultra low noise amplifier with integrated Bias Tee designed for operation from 50MHz to 4GHz in a small 15/16”x15/16”x0.59” shielded RF enclosure (PN: 6UDD2W6S1A2). At 900 MHz, the amplifier typically provides 18 dB gain, +33 dBm OIP3 at a 54 mA bias setting, and 0.8 dB noise figure. The LNA can be biased from a single supply +3V to +5V. The DC power is fed through output SMA connector. It combines Bias Tee and LNA in one with DC Power via RF output port.

    Listed pictures include Product Picture and S Parameter from 50M to 4 GHz. SKU#: AK20-001C. This LNA includes the RF Enclosure as shown in picture.
