Feature: 1. The module supports status selection function parallel port and serial port mode and power 2. The RF digital attenuator has a step of 0.5dB and a total of 6 bits. The controllable range is 0‑31.5dB, which can be used to control signal strength and also for signal modulation 3. Adopt 1.6mm thick PCB double sided board, sturdy and durable, come with long service life 4. The product have large heat dissipation area, stable operation and long running time 5. Insertion loss for only 2dB (typical value), maximum input is 20dBm (100mW), bring excellent performance Specification: Item Type: Attenuator Module Material: PCB Purpose: RF attenuator Model: PE4302 Power Supply Voltage: 3.3V Bandwidth: 1MHz~4GHz(the attenuation value will be different under different frequencies) Control Bits: 6 Bit Control Step: 0.5dB Control Range: 0-31.5dB Insertion Loss: 2dB(typical value) Ascent Speed: 0.2us Decline Speed: 0.2us Maximum Input: 20dBm(100mW). Package List: 1 x Attenuator Module Note: Do not use outside the current, voltage, and frequency range.
