Response to TCB Findings 1. Only the power cable appears to be attached to the device during radiated emissions test. Please explain why the data input port was not populated. Response: The reason there was no data cable is that baseband data is expected to flow to and from a carrier board. The only data interconnect on the OEM100 is a board to board stacking connector; there is no connector for a cable. This is consistent with the description of a carrier board in the hardware manual (see page 7). 2. Please supply the 20dB bandwidth plot for the module. The data is mentioned in the report, but the plot is missing. Response: 20dB plot supplied. 3. Have all the tests presented in this report been performed at nominal voltage of 3.6V, including previous test data used? The voltage variation data suggests that at lower voltages the power levels will drop. Please clarify. Response: The eut has a built in threshold which does not allow it to stay on beyond a certain value. All new testing was performed at the nominal value. The CEMI data is supplied in the report. In the previous application the node was battery powered only so CEMI was not done. For modular testing, it was determined that a 3.6V input to the module provided the highest output power. All testing performed specifically on the module was done at 3.6V. Antenna port conducted data for the module was taken from the original node application which was tested with a 3V battery. The maximum deviation in the POP of the device due to voltage input variations (table pg 15) is 10.8dB with the minimum power at 1.6V and the maximum at 3.6V. Since the device at 3V passed the limit by more than 20dB, the boost in power caused by 3.6V operation will be well within the limit.

DATA GUIDE “SPLATCH” PLANAR ANTENNAS INTRODUCTION The “Splatch” is a breakthrough in compact antenna technology. It combines excellent performance and cost-effectiveness into an antenna package that can be integrated, even by designers lacking RF test equipment. Despite its simplicity and ease of use the “Splatch” should not be thought of as “just any other part”. Its correct function is critical to the performance of your overall device. Dropping the “Splatch” in the center of your board like any popcorn IC will likely yield dismal results. It is critical to follow the guidelines below in order to obtain proper function. 0.062" 1 GROUNDED LINE PLANAR ANTENNA 433-SP 1.102" 0.200" 0.540" 1 1 GROUNDED LINE PLANAR ANTENNA 433-SP ANT .

Splatch antennas are supplied in tube packaging - 20 pcs. per tube. Tape and reel available at extra cost on request. ORDERING INFORMATION FEATURES: Low Cost Eliminates unsightly external antennas Easily concealed Direct PCB mounting Reflow compatible Stable grounded-line element Excellent proximity performance 10MHz approximate useable bandwidth Page 2 ATTACHMENT The antenna pads are designed to support both hand and automated placement. Castellations have been provided to ease solder introduction during hand assembly. The parts are also fully compatible with the reflow process for automated assembly. APPLICATION CONSIDERATIONS When implemented correctly the “Splatch”will yield outstanding and repeat- able results. However, the “Splatch”was designed with very specific feed and mounting requirements. Failure by the designer to respect these require- ments will result in unsatisfactory performance. * The antenna is tuned for direct mounting to a product’s PCB. Mounting the antenna in any other manner will produce poor results. * The antenna should be fed with a trace <=.25". Longer runs or coax feeds are not recommended. * Nothing should be placed under or directly beside the antenna element. Generally, mounting the antenna at the front of a product as illustrated will yield the best results. Typical Remote Control Application 1 GROUNDED LINE PLANAR ANTENNA 433-SP 418 Groundplane on Rear of Board Vias To Groundplane No Groundplane/Copper/Trace Area - BARE PCB .25" or Less Microstripped Feedline Page 3 LAYOUT CONSIDERATIONS Improper placement of planes, traces or components will result in antenna nulls or complete detuning. First, the area under the antenna on all board layers should be completely free of components, traces, or groundplane. In addition, no components or traces should pass within .25" of the top, sides, front or back of the antenna. Ideally the antenna will be mounted at the top of the board and given an unobstructed field of view in all directions. Components placed in the area below the back edge of the antenna will have little effect since the antenna has a null at its back edge when referenced appropriately to groundplane. Components placed to the sides or top of the antenna or items such as displays mounted in proximity to the antenna will produce nulls and, possibly, detuning. The antenna may be referenced to groundplanes of all different surface areas; however, it has been optimized for a 1.5"x 3" plane area. The best performance and lowest VSWR will be obtained when referenced to a plane of similar area. The recommended pad layout is illustrated below. The top layer of the board generally has the antenna mounting pads and feed trace. The ground pads are connected to the groundplane layer through vias. Use care in the sizing and placement of the vias to prevent solder migration from the attachment pads during attachment. Pads and outline shown for groundplane position reference only. Top Layer Bottom Layer Vias To Groundplane 0.100" 0.090" FEED CONSIDERATIONS Like most reduced-size antennas the “Splatch”has a fairly high Q and thus exhibits narrow bandwidth characteristics. The single most critical element in insuring the optimum function of the “Splatch”is to minimize the length of the feed trace (Transmission Line) to the “Splatch”itself. The feed trace should be less than .25" and in all cases microstripped. The term “Microstrip”refers to a trace passed over groundplane of a width appropriate to create a 50-ohm transmission line between the module and the antenna. Since the antenna does not present a true and stable 50-ohm match, the feed trace tends to lower the antenna’s resonant frequency. Given the antenna’s narrow bandwidth, it can easily be detuned by the length of the feed trace; thus, the trace should be kept as short as possible. Additional microstrip details are available in the reference section of this guide SPLATCH SERIES PERFORMANCE DATA About These Measurements The typical performance graphs below were based on a "Splatch" antenna affixed to the test jig illustrated, and measured with a HP-8753D network ana- lyzer in a 20°-25°C environment. *As of the time of this publication, full pattern characterization data was not avail- able.
