Traditional “Binary” Power Combining
Amplifying transistor element outputs are
combined using multiple stages of pair-wise
“wired” connections
Each successive stage of wiring contributes more
transmission line loss than the previous stage
Combining efficiency drops rapidly with
increasing number of elements
Increasingly inefficient as large numbers of
transistors are combined
Binary Technology Limitations…
► More energy used, more heat generated
► Larger package footprint
► Less efficient, less reliable

Spatial Power Combining
ARRAY OF INDIVIDUAL TRANSISTOR-BASED ELEMENTS
RADIATING STRUCTURES
INDIVIDUAL ELEMENT OUTPUT “BEAMLETS”
SPATIALLY COMBINED OUTPUT BEAM
Wavestream Spatial Power Advantage:
Uses array of active elements
Each element output feeds a radiating
structure
Individual element outputs are spatially
combined in a single step into a coherent
output beam
The Wavestream Difference...
► Higher output power, less heat, greater reliability
► Greater efficiency in compact, light weight packages
► Lower energy consumption, lower lifecycle costs

Spatial Power Combining- Construction Principles
Deck Amp uses solid-state devices directly
coupled to input and output fields by
antennas enclosed in waveguide
SPATIALLY COMBINED OUTPUT
Printed antennas and
chips are mounted to heat
spreader “trays”

Trays are stacked to
form the waveguide

Today’s Broadcast Industry Needs
Reduce power consumption (operational expenses). Change to high
efficiency equipment
Reduce annual maintenance expenditures- eliminate open-ended
consumables costs
Reduce footprint requirements - make room for new digital equipment
within existing facilities
Lower life cycle costs - switch to solid state-no more consumable
products
Improve on power, performance and reliability

Enter Wavestream
Wavestream has introduced the world’s first (Form, Fit, Function) solid
state alternative SSPa’s and BUC’s to existing TWTA models:
-Linearized 750 W C-band
-Non-linearized 750 W C-band
-400 W C-band
-200 W Ku-band
-100 W Ku-band
Solid State products provide same linear RF power at half of TWTA
powers
Same size, same weight, same performance, same price, same
functionality, better reliability, long-term stability, superior
environmental range
No TWT replacement again, ever
50% prime power saving in redundant mode

13. Proprietary and Confidential13
”Spatial Power Combining” Technology Advantage
Smaller size (especially for higher power levels) than tube amplifiers
Have replaced 3 kW Klystron Amplifiers and 750 W TWTA’s with our 600
W SSPA’s and BUC’s
Higher efficiency means less prime power draw
– Fewer chips, less heat generated, greater MTBF, lifecycle cost savings
Class A-B biasing results in lower power draw as RF power output
demand is lowered
Instant ”ON” capability (< 60 msec) allows redundant Amplifier to
operate in “OFF” mode, saving 50% prime power and saving capital
equipment consumption.
Technology is 100% scalable to other broadcast frequencies

14. Proprietary and Confidential14
Broad Product Portfolio
Established clear market leadership for compact, highly efficient SSPAs with a field-proven
family of Ka, Ku, X and C-band products
– Growing product portfolio for land, air and sea platforms and a variety of antenna systems
– Each product is designed and tested to meet strenuous requirements for temperature, shock
and vibration. Each product is tested over the full range of frequency and temperature.
– Delivering more than 350 HPAs per month
