The NXP power doublers CGD104xH and CGD104xHi are ideal
for use in line extenders and trunk amplifiers. They support
fiber deep-optical-node applications (N+0/1/2), delivering
the highest output power on the market today. The GaAs HFET
die process delivers high gain, excellent CTB and CSO ratings,
and lower current.
The new NXP CGY104x push-pull family is the first line-up on
the market to combine very low noise, best-in-class distortion
parameters, and low, “carbon footprint” capabilities. It delivers
the best performance for the lowest power consumption,
so it reduces OPEX and CO

emissions
All of NXP’s 1 GHz solutions are designed for durability and
offer superior ruggedness, an extended temperature range,
high-power overstress capabilities, and extremely high ESD
levels. As a result, they also reduce the cost of ownership.
The GaAs die is inserted in an HVQFN package that is then
mounted on thermal vias that manage heat transfer to the
heat sink. Temperature-control circuitry keeps the module's
high performance stable over a wide range of temperature.
Assembly is fully automated and requires almost no human
intervention, so repeatability remains very high.
