Connection (f-fo ) / fo (ppm) The SAW resonator is bidirectional and may be installed with either orientation. The two terminals are interchangeable and unnumbered. The callout NC indicates no internal connection. The NC pads assist with mechanical positioning and stability. External grounding of the NC pads is recommended to help reduce parasitic capacitance in the circuit. -200 0 +20 +40 +60 +80 T = T C - T O ( °C ) I Characterization Test Circuit Admittance Capable Network Analyzer J K L N K Power Dissipation Test N O N M M 50  Source at F C Case and Typical PCB Land Dimensions Ref A B C D E F G H I J K L M N O Min 2.87 2.87 1.12 0.77 2.67 1.47 0.72 1.37 0.47 1.17 mm Nom 3.00 3.00 1.25 0.90 2.80 1.60 0.85 1.50 0.60 1.30 3.20 1.70 1.05 0.81 0.38 Max 3.13 3.13 1.38 1.03 2.93 1.73 0.98 1.63 0.73 1.43 Min 0.113 0.113 0.044 0.030 0.105 0.058 0.028 0.054 0.019 0.046 P INCIDENT Low-Loss Matching Network to 50  P REFLECTED Inches Nom 0.118 0.118 0.049 0.035 0.110 0.063 0.033 0.059 0.024 0.051 0.126 0.067 0.041 0.032 0.015 Max 0.123 0.123 0.054 0.040 0.115 0.068 0.038 0.064 0.029 0.056 1 6 5 4 Typical Low-Power Transmitter Application Modulation Input 200k  +9VDC C1 47 L1 (Antenna) 1 6 2 3 5 4 C2 ROXXXXC Bottom View RF Bypass 470 Typical Local Oscillator Application Output 200k  C1 Equivalent RLC Model +VDC L1 0.05 pF* Cp Lm 3 Example Application Circuits +VDC Rm 2 1 Co = Cp + 0.05 pF 6 *Case Parasitics ROXXXXC Bottom View 2 3 5 4 C2 RF Bypass Cm Copyright © 2016 by RFM Integrated Device, Inc.
