Figure 4: Power-On Timing
The transmitter is packaged as a hybrid through-
hole SIP-style module with 10 pins spaced at .1"
i n t e rvals with a .3" gap between pins 2 & 3.
Baseband components occupy the rear of the board
while high-frequency components are grouped on
the front.
The SIP module may be installed using hand- or wave-solder techniques . The
module should not be subjected to reflow. If the module is subject to production
wash cycles, adequate drying time should be allowed prior to power-up. If the
wash cycle introduces contaminants, the module’s perfo rmance may be
adversely affected.
