Electronic Characteristics of 926MHz SAW Filter

EnvironmentalCharacteristics of 926MHz SAW Filter  
1. High temperature exposure
Placing the 926MHz SAW filter 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 SAW filter at -20 ℃ 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  SAW filtermust be in a place with low temperature, -40 ℃ for 30 minutes,following by a high temperature of 25℃ forfive minutes and then a higher temperature of 85℃ for 30 minutes. When the device is released into a room with normal temperatureconditions for one or two hours prior to the measurement,it shall meet the specifications 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 926MHz SAW filter shall meetthe specifications in table 1.
6. Mechanicalshock
Drop the SAW 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.  

Remarks for 926MHz SAW Filter Usage
1. Static voltage
Please avoid static voltage between signal loadand ground, it may cause deterioration or destruction of the SAW filter components.
2. Ultrasonic cleaning
Please avoid ultrasonic cleaning, it may cause deterioration ordestruction of the SAW filter components.
3. Soldering
Please avoid soldering different parts of the SAW filter components, just leads may be soldered.
