EnvironmentalCharacteristics of 947MHz Base Station SAW Filter

1. High temperature exposure
Placing the 947MHz base station SAWfilter at 85 ℃ for sixteen hoursand then releasing the filter into a room with normal temperatureconditions for twenty-four hours prior to the measurement, it shall fulfil thespecifications in table 1
2. Low temperature exposure
Placing the 947MHz base station SAWfilter at -40 ℃ for sixteen hoursand then releasing the device into a room with normal temperatureconditions for twenty-four hours prior to the measurement, it shall fulfil thespecifications in table 1.
3. Temperature cycling
The 947MHzbase station SAW filter must be in a place with lowtemperature, -40 ℃ for 30 minutes, following by ahigher temperature of 85℃ for 30 minutes. Whenthe device is released into a room with normal temperature conditions for24 hours prior to the measurement, it shall meet thespecifications in table 1.
4. Resistance tosolder heat
If the SAW filter terminals are immerse no closer than 1.5 mm into the solder bath at 260℃ ±10℃ for 10±one second an then release itinto a room with normal temperature conditions for four hours, it shall meet thespecifications in table 1.
5. Solderability
Submerge the device terminals into the solder bath at 245℃ ±5℃ for five seconds. More than 95% area of the soldering pad must be covered withnew solder; the 947MHz base stationSAW filter shall meet thespecifications in table 1.
6. Mechanicalshock
Drop the 947MHz base stationSAW filter randomly onto the concrete floor from a height of 1 m three times. The filter shall fulfil thespecifications in table 1.
7. Vibration
Subject the device to vibration for two hours each in x, y and z axeswith amplitude of 1.5 mm at 10 to 55 Hz. The filtershall fulfil the specifications in table 1.

3. Remarks for 947MHz Base Station SAW Filter Usage
3.1. Static voltage
Please avoid static voltagebetween signal load and ground, it may cause deteriorationor destruction of the base station SAW filter components.
