Our mission at GPIO Labs is to make wireless technology easy to use and fun to work with.
This is a small, cost-effective band pass filter with Bias Tee centered at 1575.42 MHz with a typical insertion loss of 3.5 dB in the pass band. An optional voltage supply can be provided using either a micro USB (cellphone) cable or DC header (+4V to +10V) to power an active antenna with 3.3V. 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.
• GPS L1 signal reception using an active antenna
• Rejection of strong signals in Cellular, LTE, UHF and 915 MHz, 2.4 GHz ISM bands
• In the Lab or out in the Field
