` Bridgers

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

2 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.
