Teledyne - I SSPI Day 2017

  1. 1. TELEDYNE Paradise Datacom A Teledyne Technologies Company lklkjlkj 1 Teledyne Paradise Datacom Taking the mystery out of SSPAs and Systems SSPI Brazil Day Paul Sandoval Director International Sales Atlanta Paul.Sandoval@Teledyne.com May 30, 2017
  2. 2. TELEDYNE Paradise Datacom A Teledyne Technologies Company TPD Portfolio-PoTs 2 1. GaAs and GaN SSPAs 2. Indoor and Outdoor • Compact OutDoor • High Power Outdoor • Rack Mountable 3. Redundancy • 1:1 and 2:1 Systems • Internal Control or Control Panel 4. FPC and Soft Fail Systems • 2+1 Fixed Phase Combined • 1+N Soft-fail Systems
  3. 3. TELEDYNE Paradise Datacom A Teledyne Technologies Company TPD Portfolio (cont) One System-Boundless Connectivity 3 Q-Flex™-DVBS2X-Pair Carrier-XstreamIP Software Definable SCPC Modem Q-NET™-SATCOM Network System Based on Q-Flex™ Q-Lite™-DVBS2X-Modem in a card
  4. 4. TELEDYNE Paradise Datacom A Teledyne Technologies Company Confusing Power Ratings Terms 4 Saturation Power (TWTA-SSPA) Filament Power (TWTA) Peak Power (TWTA) Maximum Transmit Power (TWTA) Power at 1dB compression Point (GaAs- SSPA) Power at The Flange (TWTA and SSPA) Lineal Power (various definitions) Why in the world somebody just tell me what is the usable power !!!
  5. 5. TELEDYNE Paradise Datacom A Teledyne Technologies Company 5 Linear Output Power, Plinear Intermod Level, -25 dBc Spectral Regrowth, -30 dBc Amplifier Output Signal The most important output power parameter is the linear output power, Plinear. The Plinear rating of an amplifier is the maximum output power at which: -25 dBc intermod can still be achieved with a two-tone intermod test -30 dBc spectral regrowth on a single carrier digitally modulated signal Plinear is achieved at 3 dB back from Psat. Thus an 1000W Psat SSPA produces 500W Plinear output power
  6. 6. TELEDYNE Paradise Datacom A Teledyne Technologies Company SSPA Technology • GaAs • Nearly Class A mode of operation. • Lower Power Devices than GaN • Better Linearity at low output power levels. • P-linear = P1 - 3dB • GaN • Class AB mode. • Much higher power transistors. • Same Linearity as GaAs at high output power levels (when linearized). • P-linear = P-sat-3dB (linearized) • P-linear = P-sat-4dB (not linearized) 6 Paradise Datacom
  7. 7. TELEDYNE Paradise Datacom A Teledyne Technologies Company Power Combining Architecture 7 Automatic Gain Correction
  8. 8. TELEDYNE Paradise Datacom A Teledyne Technologies Company Outdoor PowerMAX Systems 8 8-Module PowerMAX architecture based on the High Power Outdoor Enclosure. High Power Outdoor SSPAs easily slide out on shelf for easy access and maintainability Modular 3kW Ku Band Outdoor System Comprised of (8) 400W Ku Band GaN SSPAs RF Distribution Box AC Distribution Box System Controllers
  9. 9. TELEDYNE Paradise Datacom A Teledyne Technologies Company 9 8 Module GaN PowerMAX Systems
  10. 10. TELEDYNE Paradise Datacom A Teledyne Technologies Company 8 Module GaN PowerMAX Systems 10
  11. 11. TELEDYNE Paradise Datacom A Teledyne Technologies Company Summary • A complete portfolio of GaN and GaAs SSPA Products that can be applied to solve most HPA applications. • Extremely High Power SSPAs available from L/S-Band up through Ka Band. • Single Thread, Redundant, Phase Combined Solutions • Phase Combined Solutions in Outdoor as well as Indoor Enclosures. 11
  12. 12. TELEDYNE Paradise Datacom A Teledyne Technologies Company Useful • Back-Off • Single Carrier; 1 dB • Two Equal Carriers; 3 dB • Multiple Carriers; 4 dB (6 dB for older non linearized TWTA) • Logarithms factors • 3 dB x 2 • 1 dB x 1.25 • 2 dB x 1.6 • 4 dB x 2.5 12
