RO3144E

AEC-Q200 This component was always RoHS compliant from the first date of manufacture. RO3144E • • • • • Ideal for 916.5 MHz Remote Control and Data Telemetry Transmitters Very Low Series Resistance Quartz Stability Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 RoHS 916.5 MHz SAW Resonator Compliant The RO3144E is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount ceramic case. It provides reliable, fundamental-mode stabilization of fixed-frequency transmitters operating at 916.5 MHz. This SAW is designed specifically for remote control and data telemetry transmitters operating in the USA under FCC Part 15 regulations and in Canada under DoC RSS-210.

Connection 0 -50 -50 -100 -100 -150 -150 (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 -80 -60 -40 -20 H 6 1 5 2 4 3 -200 0 +20 +40 +60 +80 T = TC - T O ( °C ) I Characterization Test Circuit Inductor LTEST is tuned to resonate with the static capacitance, CO, at FC. 3 4 D J 6 1 From 50  Network Analyzer 5 2 4 3 To 50  Network Analyzer K L N K N Power Dissipation Test 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 2 3 5 4 C2 *Case Parasitics ROXXXXC Bottom View RF Bypass Cm ©2010-2015 by RFM Integrated Device, Inc.
