Introduction
RoyalTek REB-3300 low power and small form factor board is the newest generation of
RoyalTek GPS Receiver. The GPS receiver is powered by SiRFStarIIe/LP technology with
XTrac 2.0 firmware and RoyalTek proprietary navigation algorithm that providing you more
stable navigation data. The smallest form factor and miniature design is the best choice to be
embedded in a portable device like PDA, personal position and navigation like personal locator,
speed camera detector and vehicle locator. The excellent sensitivity of REB-3300 gets the
great performance when going though the urban canyon and foliage.

Application Circuit
(1) Ground Planes:
REB-3300 GPS receiver needs two different ground planes. The GND_A pin(11、
12、13、14、15、16、18) shall be connect to analog ground.
The GND pin(2、10、30) connect to digital ground.
(2) Serial Interface:
The Serial interface pin(RXA、TX1、TXB、RXB) is recommended to pull up(10KΩ).
It can increase the stability of serial data.
(3) Backup Battery:
It’s recommended to connect a backup battery to V_BAT.
In order to enable the warm and hot start features of the GPS receiver. If you don’t
intend to use a backup battery, connect this pin to GND or open.
If you use backup battery, shall need to add a bypassing capacitor (10uF) at V_bat

trace. It can reduce noise and increase the stability.
(4) Antenna:
Connecting to the antenna has to be routed on the PCB. The transmission line must
to controlled impedance to connect RF_IN to the antenna or antenna connector of
your choice.
(5) Active antenna bias voltage:
The Vcc_RF pin(pin 20) is provide voltage 3.0V. If you use active antenna, you can
connect this pin to V_ANT_IN pin (pin 19) to provide bias voltage of active antenna.
The bias voltage will through RF_IN pin to provide active antenna bias voltage from
Vcc_RF pin.
If your bias voltage of active antenna isn’t 3.0V, you can input bias voltage to
V_ANT_IN pin(pin 19).And input bias voltage of you need. It can open if you use
passive antenna. The input bias voltage will through RF_IN pin to provide active
antenna bias voltage from V_ANT_IN pin.
The maximum power consumption of active antenna is about 100mW
(6) Power:
Connect Vcc pin to DC 3.3V.The power supply must add bypassing capacitor(10uF
and 1uF).It can reduce the Noise from power supply and increase power stability.
