10.8 VANT Pin

The VANT pin is an input pin.

The supply voltage for an active GPS antenna on the ANT input has to be fed into the

Vant pin. The easiest way to do that is to connect Vcc to VANT. The maximum cur-

rent is 50 mA.

Note: Shortcut between ANT and GND may damage the A2200-A GPS receiver

module. This should be avoided by using an antenna current limiter.

The circuit (chapter “10.7.2 Antenna Sensor with Current Limiter”) works for Vcc from

3V to 5V. The antenna current will be limited to 50 mA approximately.

If other transistors are used, other resistor values may be necessary as well. We

strongly recommend simulating and testing your realized version before using it.
