Richardson RFPD announces LDMOS RF power transistors for UHF broadcast
Richardson RFPD has announced the availability of two 50V LDMOS RF power transistors, setting a new standard for ruggedness in the UHF broadcast industry.
The MRFE6VP8600H and MRFE6VP8600HS are push-pull power transistors that provide enhanced efficiency and operate over the 470MHz to 860MHz frequency band.
These devices are capable of transmitting highly linear, 125W average DVB-T output power, with a peak envelope power output capability of more than 600W.
Moreover, these devices are fully capable of withstanding a nearly 100 percent mismatched load, specified as greater than 65:1 VSWR at all phase angles, with no damage to the transistor. Ultimately, the MRFE6VP8600H and MRFE6VP8600HS provide a unique combination of linear power amplification, high efficiency and enhanced ruggedness never before seen in the UHF broadcast industry.
