New microwave and mm-wave applications for the telecommunication and automotive market:

● ku and ka-band VSAT● 24 GHz short range radar● others

�� Success depends on final cost for RF module

The Chicken - Egg Problem

volume increase(�� mass production)market growth

cost reduction

HOW TO SOLVE?

Module Cost

◆ Material● package / housing● substrate● MMICs and passive devices● others

◆ Assembly / manufacturing● die attach● wire bonding

◆ Testing and tuning● measurements● tuning● burn-in

Point-to-multipoint transceiver module: Cost for RF modules:MMICs (active devices) 30-35%other materials 5%package / housing 15%assembly / manufacturing 20%testing and tuning 30-25%




26-Apr-03page 9

What limits market introduction of mm-wave point-to-multipoint systems?

◆ Cost for user: equipment and installation● ownership model : was too expensive● leasing / fee model requires low investment costs

◆ Content to be distributed : was not available!● originally video-on-demand● today: broadband / fast internet

◆ Competition:● ADSL● Cable TV● MMDS● VSAT

VSAT power lineup have to be very cheap or will never happen !

VSAT Ku and Ka-band

Frequency allocation for VSAT in Ku and Ka-band:

◆ VSAT frequencies in Ku-band:● Transmit (ground segment): 14.00 – 14.50 GHz● Receive (ground segment): 10.95 – 12.75 GHz

◆ VSAT frequencies in Ka-band:● Transmit (ground segment): 29.50 – 30.00 GHz● Receive (ground segment): 17.70 – 20.20 GHz

KEY component for VSAT applications is the high power amplifier (HPA)

◆ Classes of power required for both frequency bands:● 1 Watt power amplifier (+30dBm)● 2 Watt power amplifier (+33dBm)● 4 Watt power amplifier (+36dBm)

◆ HPAs to be operated in saturation, but are more and more used near P-1dB, for linearity raisons (side-lobe re-growth)

Flange Mount Package

◆ Standard packaging technology for Ku-band HPA● ceramic layer with leads

mounted on Cu-composite heat sink● MMIC soldered (AuSn) directly on heat sink● capacitors incorporated to avoid oscillations● standard bondwires can be used

◆ Advantages:● good electrical performance for Ku-band applications● excellent heat transfer due to Cu-composite base● well know and proven concept (qualified by system houses)

◆ Disadvantages:● volume testing difficult to perform● high cost for package (> 10 USD) and assembly (manual lead soldering)

Conclusions

◆ United Monolithic Semiconductors is the leading European source for microwave and mm-wave ICs

◆ VSAT is a volume market requiring low cost components / materials and assembly methods

◆ UMS has developed several MMICs for these applications● HPA for Ku-band VSAT (e.g. CHA6042)● HPA for Ka-band VSAT (e.g. PO-PA9981)● size reduction due to advanced design concepts leads to lower cost

◆ Packaging allows to simplify the assembly and to use pre-tested components

● flange mount package with Cu-composite heat sink● QFN package

◆ ESA Contract: Low Cost 30GHz SSPA
