AD584_Pro_V1.1

Overview

The AD584 calibration module includes a VI constant current source converter circuit, which can be connected in series with an ammeter to measure current.
The input power supply references the input voltage of the AD584 and the input voltage (30V) of the LM358, and also considers the voltage rating of the power supply capacitor;
this facilitates simple calibration of 3.5-digit voltage and current readings.
Larger packages of the constant current source resistor can be used to obtain higher constant current values.

Power divider (combiner)

A device that splits the energy of one input signal into two or more outputs of equal or unequal energy, and conversely, can combine the energy of multiple signals into one output.

Devices that split one input signal into two or more outputs of equal or unequal energy, or conversely, combine multiple signal energies into one output!
1. There are two PCB options; the second is cheaper, the first chip is too expensive!
2. Buy the SMA connector according to your needs!
PCB1 details:
Insertion loss: 0.9dB; Frequency range: 500MHz-2.5GHz;

PCB2 details:
For 699-960MHz / 1710-2690MHz,
this is suitable for receiving signals from dual-antenna LTE networks.
