Our mission at GPIO Labs is to make wireless technology easy to use and fun to work with.
This is a small, cost-effective bandpass filter with Bias-Tee centred at 1575.42 MHz with a typical insertion loss of 3.5 dB in the passband. An optional +5V supply can be provided using either a micro USB cable or DC header to power an active antenna. Alternatively, the device can be used as a bandpass filter without the supply.
This filter has excellent rejection specifications. Rejection at 850 MHz and 1615 MHz for instance, is greater than 40 dB. The filter also provides power handling of up to a maximum +10 dBm and has an operating temperature range of -40C to +85C.
Passband: 1575 +/- 7.5 MHz
Frequency --- Typical Attenuation
850 MHz --- 45 dB
1500 MHz --- 30 dB
1535 MHz --- 30 dB
1615 MHz --- 45 dB
1640 MHz --- 45 dB
1700 MHz --- 50 dB
The filter uses SMA-F PCB edge mount connectors.
Maximum DC voltage on input or output: +25V
Maximum RF input signal Level: +10 dBm
