9522A L-Band Transceiver Product Information Guide
V1.1 032405
3.3.2 Antenna Connector
The 9522A LBT provides a single 50 Ω , TNC type antenna connector both transmit and receive.
3.3.3 SIM Chip Reader
An integrated SIM chip reader is provided on the 9522A LBT. This connector allows installation of the
chip form of the SIM beneath a cover plate on the 9522A LBT housing.
3.4 Mounting
The 9522A LBT incorporates (6) mounting holes on its bottom surface that can aid in its mounting. See
Figure 3 for locations of these features. It is recommended that a thread-forming screw be used to mount
the 9522A LBT via these features. Particularly, a Textron Camcar® Taptite® II Thread-Rolling Fastener of
M3.5x0.6 thread type is recommended. This fastener has a 15IP Torx Plus® pan head and is available in
lengths of 6, 8, 12, 16, and 20 mm as part number 3BE-P802-00, 3BE-P803-00, 3BE-P8185-00, 3BE-
P804-00, 3BEP8186-00, and 3BE-P8187-00 respectively. Length should be chosen to ensure that
penetration into the 9522A LBT housing does not exceed 11 mm. If a 6-32 thread type is desired, a
Textron Camcar® Taptite® II Thread-Rolling Fastener with a 15IP Torx Plus® pan head is available in
lengths of 1/4, 5/16, 3/8, 1/2, 5/8, 3/4, and 1 inch as part number 3BE-P814-00, 3BE-P8123-00, 3BE-
P815-00, 3BE-P816-00, 3BE-P8124-00, 3BE-P817-00, and 3BE-P818-00 respectively. A 10IP Torx Plus®
flat head version is also available in a single length of 1/2 inch as part number 3BE-P801-00. Another 6-32
thread type option is to insert a helical coil insert with a 6-32 internal thread into these features thus
accommodating 6-32 threaded fasteners as mounting hardware for the 9522A LBT. National Aerospace
Standard NASM122238 serves as a technical reference for the recommended helical coil insert.
3.5 Connector Sealing in Harsh Environments
If the 9522A LBT is to be used in a harsh environment with exposure to high humidity or water, the mating
of the multi-interface connector must be further sealed to protect from moisture entry. It is recommended

connector where shown in Figure 6 below. A material similar to Permatex 16B should be used.
