High Frequency PCB Made on TMM6 | Rogers TMM6 RF PCB

 

Hi,

Good day. Hope this email finds you well.

 

TMM6 PCB's are ceramic, hydrocarbon, thermoset polymer microwave composites designed for high reliability stripline and microstrip applications. With DK 6.3, It has an exceptionally low thermal coefficient of dielectric constant, typically less than 30 ppm/°C. The thermal conductivity is approximately twice that of traditional PTFE/ceramic PCB's.

  "I was driven thence by foul winds for a space of nine days upon thesea, but on the tenth day we reached the land of the Lotus-eater,who live on a food that comes from a kind of flower. Here we landed totake in fresh water, and our crews got their mid-day meal on the shorenear the ships. When they had eaten and drunk I sent two of my companyto see what manner of men the people of the place might be, and theyhad a third man under them. They started at once, and went about amongthe Lotus-eaters, who did them no hurt, but gave them to eat of thelotus, which was so delicious that those who ate of it left off caringabout home, and did not even want to go back and say what had happenedto them, but were for staying and munching lotus with theLotus-eater without thinking further of their return; nevertheless,though they wept bitterly I forced them back to the ships and madethem fast under the benches. Then I told the rest to go on board atonce, lest any of them should taste of the lotus and leave off wantingto get home, so they took their places and smote the grey sea withtheir oars.   "We sailed hence, always in much distress, till we came to theland of the lawless and inhuman Cyclopes. Now the Cyclopes neitherplant nor plough, but trust in providence, and live on such wheat,barley, and grapes as grow wild without any kind of tillage, and theirwild grapes yield them wine as the sun and the rain may grow them.They have no laws nor assemblies of the people, but live in caves onthe tops of high mountains; each is lord and master in his family, andthey take no account of their neighbours.   "Now off their harbour there lies a wooded and fertile island notquite close to the land of the Cyclopes, but still not far. It isoverrun with wild goats, that breed there in great numbers and arenever disturbed by foot of man; for sportsmen- who as a rule willsuffer so much hardship in forest or among mountain precipices- do notgo there, nor yet again is it ever ploughed or fed down, but it lies awilderness untilled and unsown from year to year, and has no livingthing upon it but only goats. For the Cyclopes have no ships, noryet shipwrights who could make ships for them; they cannot thereforego from city to city, or sail over the sea to one another's country aspeople who have ships can do; if they had had these they would havecolonized the island, for it is a very good one, and would yieldeverything in due season. There are meadows that in some places comeright down to the sea shore, well watered and full of lusciousgrass; grapes would do there excellently; there is level land forploughing, and it would always yield heavily at harvest time, forthe soil is deep. There is a good harbour where no cables arewanted, nor yet anchors, nor need a ship be moored, but all one has todo is to beach one's vessel and stay there till the wind becomesfair for putting out to sea again. At the head of the harbour there isa spring of clear water coming out of a cave, and there are poplarsgrowing all round it.   "Here we entered, but so dark was the night that some god musthave brought us in, for there was nothing whatever to be seen. A thickmist hung all round our ships; the moon was hidden behind a mass ofclouds so that no one could have seen the island if he had lookedfor it, nor were there any breakers to tell us we were close inshore before we found ourselves upon the land itself; when, however,we had beached the ships, we took down the sails, went ashore andcamped upon the beach till daybreak.   "When the child of morning, rosy-fingered Dawn, appeared, we admiredthe island and wandered all over it, while the nymphs Jove's daughtersroused the wild goats that we might get some meat for our dinner. Onthis we fetched our spears and bows and arrows from the ships, anddividing ourselves into three bands began to shoot the goats. Heavensent us excellent sport; I had twelve ships with me, and each ship gotnine goats, while my own ship had ten; thus through the livelong dayto the going down of the sun we ate and drank our fill,- and we hadplenty of wine left, for each one of us had taken many jars fullwhen we sacked the city of the Cicons, and this had not yet run out.While we were feasting we kept turning our eyes towards the land ofthe Cyclopes, which was hard by, and saw the smoke of their stubblefires. We could almost fancy we heard their voices and the bleating oftheir sheep and goats, but when the sun went down and it came on dark,we camped down upon the beach, and next morning I called a council.
