Bolton Technical

Bolton Technical 20dB LNA Amplifier 100k-6GHz Bias Tee 2 in 1 accessory

SKU CH-RZ5B-C430X

A 100 kHz to 6 GHz low-noise amplifier delivers 20 dB gain with a 0.4 dB noise figure at 1.95 GHz, +35 dBm output IP3 and +22 dBm continuous input power, powered through an integrated bias tee

  • Ultra-low 0.4 dB noise figure at 1.95 GHz for clean signal reception
  • 20 dB gain across 100 kHz to 6 GHz for strong amplification
  • +35 dBm output IP3 linearity handles demanding RF environments
  • +22 dBm continuous input power tolerance protects against overload
  • Bias tee power supply delivers up to 1 A without external batteries

Wideband RF Signal Amplification

This Bolton Technical accessory combines a low-noise amplifier and bias tee in a single unit for RF signal conditioning. It covers a continuous frequency range from 100 kHz up to 6 GHz, making it suitable for wideband receiver front-ends and test setups. The integrated bias tee delivers DC power over the RF path, eliminating the need for separate battery packs or external power wiring.

Engineers Needing Low-Noise Gain

The amplifier suits engineers and technicians who require 20 dB of gain with a 0.4 dB noise figure at 1.95 GHz for weak-signal reception. Its +35 dBm output IP3 and +22 dBm continuous input robustness support high-linearity applications such as spectrum monitoring and software-defined radio front-ends. Builders who need a different gain value, a narrower band filter, or an amplifier without integrated bias powering should consider other options.

0.4 dB Noise Figure at 1.95 GHz

The 0.4 dB noise figure at 1.95 GHz is the key specification that determines whether this amplifier preserves the sensitivity your system needs. At this frequency the unit also delivers 20 dB gain, +35 dBm output IP3 and +22 dBm continuous input handling. If your link budget demands a lower noise figure or your operating frequency sits outside the 100 kHz to 6 GHz range, this part will not meet the requirement.

Questions about this item

How do I pick the right version or capacity of this 20 dB LNA amplifier for my setup?

The unit is a single 20 dB gain model covering 100 kHz to 6 GHz with a built-in bias tee; no alternative versions or capacities are offered.

What does the 0.4 dB noise figure at 1.95 GHz mean when the amplifier is installed in a real receiver chain?

It adds only 0.4 dB of noise at 1.95 GHz while providing 20 dB gain, so the system noise floor is barely raised and weak signals become usable.

How does the bias-tee power interface limit the amplifier in practice?

The bias tee draws up to 1 A from the connected device, so the host must supply that current; continuous RF input is capped at +22 dBm and output IP3 reaches +35 dBm.
