ZN3380C

The Beijing Daze Technology ZN3380C is a low-noise preamplifier covering 1 kHz to 18 GHz, designed for small signal reception and measurement applications requiring high sensitivity and wide dynamic range. With a minimum detectable signal of -127 dBm and up to 30 dB of gain across its operating range, it is particularly well-suited for shielding effectiveness testing and other applications where detecting extremely weak signals across a broad frequency range is essential.

Gain is specified in three bands: 30 ±2.5 dB from 5 kHz to 500 MHz, 28 ±2.5 dB from 500 MHz to 1 GHz, and 30 ±2.5 dB from 1 GHz to 18 GHz. The front panel features dedicated measurement range buttons for 1 kHz–30 MHz, 30 MHz–1 GHz, and 1 GHz–18 GHz, along with 50 Ω signal input and output terminals and a power switch. The rear panel includes a grounding terminal, AC220V power socket, and a 0.5A fuse holder.

Power consumption is less than 10W, making it well-suited for continuous long-term operation. Input signals should not exceed -60 dBm to avoid damage to the unit. Physical dimensions are 145 × 30 × 240 mm with a weight of approximately 3 kg. Each unit ships with a power cable, spare fuse, and N-N cable, and carries an 18-month warranty from the date of shipment.
