Product catalog summary

Overview
ORBIT introduces a triple-band feed system designed for cost-effective migration to C-band frequencies, addressing the telemetry market's shift from L and S bands. This system supports simultaneous operation across L, S, and C bands, utilizing concentric coaxial cavity technology to accommodate any antenna reflector size.

Key Features

Simultaneous support for L, S, and C bands.
High G/T performance and wide-range tracking capabilities.
Auto-tracking with a single channel mono-pulse technique.
No cross-over gain reduction at boresight and efficient reflector illumination.
Low axial ratio and single feed supporting all three bands.

Technical Specifications

Frequency Range: L(Low) 1435-1525 MHz, L(High) 1755-1850 MHz, S 2200-2400 MHz, C 4400-5150 MHz.
Scan Rate: 10-1,000 Hz (user selectable).
F/D Ratio: 0.37-0.45.
Polarization: Simultaneous LHCP and RHCP.
VSWR: <2.0:1 on output ports.

AL-1100-LSC L, S & C Triple-Band, Auto-Tracking Feed Typical Applications Missile Launch Tracking Aeronautical Test Telemetry Supported Bands L(Low) Innovative, High-Performance Solution for Cost-Effective Migration to C-Band In response to the telemetry market’s growing adoption of C-band frequencies – in addition to L and S bands commonly used today - ORBIT’s new triple-band feed system provides a state-of-the-art solution for simultaneous operation in multiple telemetry communication frequency bands. Based on its concentric coaxial cavity technology, ORBIT can offer a single feed supporting all three bands for any antenna reflector size. ORBIT’s patent pending triple-band feed can simultaneously receive L, S and C bands and auto-track any of those bands per customer configuration. ORBIT’s triple-band is the perfect solution for customers who wish to upgrade their operational legacy tracking system to support high performance C-band at a fraction of the cost of a new system.  Simultaneous support of L, S & C bands  High G/T performance  Wide-range tracking capabilities  Auto-tracking using single channel mono-pulse technique  Single feed supporting all three bands  No cross-over gain reduction at boresight  Efficient reflector illuminat
