TRANSMITTER DESCRIPTION The 13.56Mhz crystal (Y1) generates the main oscillator signal used in the transmitter circuit. This signal is applied to the gate (U1A) which controls the carrier on/off sequence. The carrier is then passed through gate (U1D) which inverts the “off” dc level which prevents power consumption of the level shifter (Q6).The level shifted carrier is coupled to (Q6) through RC circuit C12 and R14. This places the power amplifier (Q6) in class C mode which minimizes overall power consumption. Impedance matching and low pass filtering are provided by the Pi filter (C13, L3, and C14). The antenna Q and resonance are provided by R11 and C9. MODULATION Direct amplitude modulation is applied to the circuit through Q2 and R3. Q2 fully saturated provides full carrier amplitude with R3 reducing the carrier by 30% with Q2 being cut off.

(PDA does not operate correctly below –11°C) FCC Application for TEK Industries, Inc.••FCC ID: P7PPROTEGE •• Report No. EC0014-1 25-Apr-02 ______________________________________________________________________ _____________________________ ________________________________ Curtis-Straus LLC •• 527 Great Road •• Littleton, MA •• TEL (978) 486-8880 •• FAX (978) 486-8828 page 4 of 14 Test Methodology Radiated emission testing was performed according to the procedures in ANSI C63.4 (1992). The testing was performed at an antenna to EUT distance of 3 or 1 meters below 30MHz, and 3 meters above 30MHz. The actual test distance used is noted in the test data sheets. The device’s performance was investigated to 1GHz. The EUT was powered by four rechargeable batteries. Freshly charged batteries were used for all testing. Since the device is a hand-held unit, the emissions were maximized around the three orthogonal axes and the maximum reading was recorded. The integrated antenna cannot be maximized separately. The frequency stability test consisted of varying the temperature of the product in a temperature chamber while monitoring the peak of the fundamental frequency, and taking measurements when the product’s temperature stabilizes. All other performance tests were made in accordance with the procedures outlined in Part 15 of CFR 47. The applicable sections provided under Part 15 are provided in the measurement section of this report.
