ZN3380A

The Beijing Daze Technology ZN3380A is a low-noise preamplifier covering 1 GHz to 40 GHz, designed specifically for small signal reception and measurement applications requiring high sensitivity and wide dynamic range. With a minimum detectable signal amplitude of -127 dBm and a typical gain of 25 dB, it is particularly well-suited for shielding effectiveness testing where detecting extremely weak signals across a broad frequency range is essential.

Key specifications include a noise figure of less than 2, frequency response flatness of ±2 dB across the full 1–40 GHz range, and a 220V ±10% / 50 Hz power supply. The unit features a switchable measurement range: in standard mode it covers 1 GHz to 18 GHz, and when the red button is pressed the range extends to cover 18 GHz to 40 GHz — providing flexibility for measurements across the full operating bandwidth. Users should avoid input signals stronger than -60 dBm to prevent damage to the amplifier.

The ZN3380A carries an 18-month warranty from the date of shipment, covering defects under normal use and transportation conditions.
