The TSL Series 1100 products include a complete line of pulsed L-Band airborne amplifiers and transmitters suited for Identification Friend-or-Foe (IFF) and for Traffic Collision Avoidance Systems (TCAS) applications. Models are available that comply with IFF Modes 1, 2, 3A & C, 4, ,5, and Mode S-ELM designed to meet the demanding standards of DoD AIMS97-1000, RTCA/DO-181C, and STANAG 4193. Series 1100 products are in use worldwide in IFF Transponders and in the US Army Model PPX-3 IFF Interrogator.
The Series 1100 is a state-of-the-art power amplifier utilizing the latest in Bipolar and LDMOS technologies. Designs include Differential Phase Shift Keying (DPSK) modulation providing digitized cosine form transitions for rise and fall times. Some models are available with High Speed Pulse Suppression.
