The streamline person who conveys UHF of power transistor is designed
Freescale semiconductor released and designed by transistor of MRF6V3090N RF power which aims at streamlined UHF telephone transmitter apparatus. As MRF6VP3450H that has concurrently enables can save value to reduce potentially while becoming possible as one grade of power of system of the operation expenses of thousands of dollars for the announcer, 50 V only LDMOS transistor.
The telephone transmitter represents quite a lot of operation expenses for the TV announcer, and it is power that amplifier of RF power consumes to bring to the donor and operate expenses to this. Very efficient transistor of RF power, such as MRF6V3090N and MRF6VP3450H, can help through until heavy percentage change into RF output power reduce expenses this DC input power that require. In addition, the specific transistor improves one grade of efficiency of system together with high RF power ability so that reduce to the minimum apparatus and count and accord with losses.
Freescale broadcasts the newest increase which employs the family which increases RF power LDMOS transistor, MRF6V3090N utilizes the modulation form of simulation and figure to be designed for the telephone transmitter of the TV. MRF6V3090N sends power of 90 W peak value and passes UHF which broadcast the belt of frequency with greater than 4,000 of the efficiencying together in P1dB.
As a driver of line, on the basis of a DVB-T OFDM signal, MRF6V3090N makes power of 21 decibels and gains 12% that and the average output power with 4.5 W consumed efficiency gradually. It is in a 4 kHz comprehensive bandwidth that the adjoint channel ability rate of 4 MHz compensated is – 68 dBc. As low power repeater last one analogue TV or DTV, apparatus those have typical UHF broadband performance greater than 40% of the efficiency, 21 decibels got less than – 30 dBc with IM3.
Lay too stale plastics to encapsulate technology in Freescale, those MRF6V3090N can be used a single room inclusive to finish or push away and draw the structure. This enables design engineer to use the apparatus in expecting much reaping and much application and belt of efficiency.
The transistor is taking a sample now, and the abundant products are being expected in Q4 09. Consult and test the fixed apparatus can be offered and facilitated assessing, design and deal with.
