All specifications are based on the test circuit shown below 2. Device will function over the storage temperature range (-40 to +85 deg C). However, specifications are only guaranteed at the operating temperature of 25 deg C. The temperature coefficient will define the frequency shift over temperature. 3. This is the optimum impedance in order to achieve the performance shown Test Circuit: Actual matching values may vary due to PCB layout and parasitics 120nH 100nH 11 5 50 1,2,3,4,6, 50 Single-ended 50 7,8,9,10,12 Subject to change or obsolescence without notice Rev - 09-Dec-2003 Page 2 of 5
