I have a copy of the SenSym 1984 Pressure Sensor Handbook, 1255 Reamwood Avenue
Sunnyvale, Ca 94089  (408) 744-1500.

On page 9-35 is applications note ssan-12 which describes a solid-state
altimeter for Transponder Applications.  

This is basically a barometer using their LX1802AN absolute pressure 
transducer.

Hope this helps.
