Legal limit heat sink and copper heat spreader module
LINEAR DUAL LDMOS POWER AMPLIFIER ON A COPPER HEAT SPREADER AND EXCELLENT HEAT SINK. This module is designed for two LDMOS-FET's operating in a push-pull circuit. A Variety of RF LDMOS-FET'S can be mounted on the board. If BLF188XR are used, devices are operated at 1/2 of their rated power output thus. Having a great headroom and fantastic gain (22-24db) and much better IMD figures.
A thermal cutout fuse is also mounted for over temp protection. The board has enough "headroom" to cover up most minor operating mistakes.The LDMOS devices with the "XR" are Extremely rugged devices!! The amplifiers have very good IMD since the devices are designed to loaf along at the designed power level. They are not pushed to the limit or to saturation! I was asked a few questions by members so here is my added reply. Amps are made for 160-6m.
Slight trade off to set the right balance in power/bandwidth so there is. About 10% drop on 6.Duty cycle is very good and with proper cooling of forced air it will do full duty cycle! Cores are large and many thus an.
Average rise of core temperature is also controlled As a result I have not. Seen core failure or saturation and far away from curie point.A good power supply that can be used with my amps or boards can be found. Please verify your address during checkout.
