  • z(DISCONTINUED) 145 MHz Filter/Preamp

    0 out of 5

    Uputronics filtered preamps for improved reception on 145Mhz.

    This is a cost effective SAW based unit which give excellent performance gains.

    All Uputronics preamps are compatible with most USB SDR Dongles such as the Airspy. You can power them from either bias tee (This item is 100% compatible with the Airspy bias-tee) or a simple USB minicable (Purchased separately). Bias tee/USB voltage is 5V max.

    This unit is a small filter and preamp designed to go between a software defined radio receiver and an antenna. Using a SAW bandpass filter and a low noise amplifier (LNA), it stops out of band intermodulation while providing additional gain for increased sensitivity. The LNA is before the SAW filter. To block strong commercial FM signals a high pass filter is installed before the LNA.

    The LNA used is a MiniCircuits PSA4-5043+ which provides at least 21dB of gain. To stop out of band intermodulation a 145Mhz SAW bandpass filter, which has a 7.6MHz bandwidth is also present. The insertion loss of this filter is approximately 1.4dB, which does increase the overall noise figure of the unit to 0.75dB. Connectors are SMA female both sides.

    Uputronics filtered preamps for improved reception on 220Mhz.

    This is a cost effective SAW based unit which give excellent performance gains.

    All Uputronics preamps are compatible with most USB SDR Dongles such as the Airspy. You can power them from either bias tee (This item is 100% compatible with the Airspy bias-tee) or a simple USB mini cable (Purchased separately). Bias tee/USB voltage is 5V max.

To block strong commercial FM signals a high pass filter is installed before the LNA.

    The LNA used is a MiniCircuits PSA4-5043+ which provides at least 20dB of gain. To stop out of band intermodulation a 220Mhz SAW bandpass filter, which has a 7MHz bandwidth is also present. The insertion loss of this filter is approximately 2.3dB, which does increase the overall noise figure of the unit to 0.75dB. Connectors are SMA female both sides.

    0 out of 5

    This is an assembled breakout board with a uBLOX MAX-M8Q module, front end LNA and Filter.

    The board incorporates an Infineon front end SAW filter and LNA for enhanced performance and faster lock times.

    We have two versions available. This one is suitable for 3.3V microcontrollers and logic levels.

    Suitable for HAB Usage Max Altitude 50,000 meters / 164041 feet in Flight Mode.

    The module is supplied with a 2.54mm 8 way header and a super cap for hot start/setting retention.

    The board is constructed on 1.6mm PCB and utilities the Sarantel/Maruwa SL-1252 Quadrafilar Antenna offering great omnidirectional performance and rejection of out of band signals.

    On the header are TX, RX, EN(Enable – turns on the level convertor on 5V boards), TP (PPS Output), 3/5V Supply I2C SCL/SDA and GND.

    The MAX-M8Q delivers all the benefits of the u-blox 8 GPS platform in a more compact form factor than ever before: high-sensitivity, intelligent power management.

    Supporting temperatures down to -40’C and featuring a TCXO for better power saving and quicker startup.

    The breakout has the following dimensions :

    3V Version 48.5mmx21mm (board edge to top of antenna) x1.6mm (13.2mm antenna diameter) approximately – Weight 10g

    As per the data sheets the MAX M8Q can use up to 22mA under acquisition (5mA in power save mode once tracking).

    The default baud rate is 9600bps.
