mitsubishi rf mosfet module ra45h8994m1 rohs compliance, 896-941mhz 45w 12.8v, 2 stage amp. for mobile radio ra45h8994m1 mitsubishi electric 7 dec 2009 1/9 electrostatic sensitive device observe handling precautions description the ra45h8994m1 is a 45-watt rf mosfet amplifier module for 12.8-volt mobile radios that operate in the 896- to 941-mhz range. the battery can be connected dire ctly to the drain of the enhancement-mode mosfet transistors. without the gate voltage 1 and the gate voltage 2(v gg1 =v gg2 =0v), only a small leakage current flows into the drain and the nominal output signal (p out =45w) attenuates up to 60 db. when fixed i.e. 3.4v, is supplied to the gate voltage 1, the output power and the drain current increase as the gate voltage 2 increases. the output power and the drain current increas e substantially with the gate voltage 2 around 0v (minimum) under the condition when the gate voltage 1 is kept in 3.4v. the nominal output power becomes available at the state that v gg2 is 4v (typical) and 5v (maximum). at this point, v gg1 has to be kept in 3.4v . at v gg1 =3.4v & v gg2 =5v, the typical gate currents are 0.4ma. this module is designed for non-linear fm modulation, but may also be used for linear modulation by setting the drain quiescent current with the gate voltages and controlling the output power with the input power. features ? enhancement-mode mosfet transistors (i dd ? 0 @ v dd =12.8v, v gg1 =v gg2 =0v) ? p out >45w, t >33% @v dd =12.8v, v gg1 =3.4v, v gg2 =5v, p in =50mw ? broadband frequency range: 896-941mhz ? metal cap structure that ma kes the improvements of rf radiation simple ? low-power control current i gg1 +i gg2 =0.4ma(typ) @ v gg1 =3.4v, v gg2 =5v ? module size: 67 x 18 x 9.9 mm ? linear operation is possible by setting the quiescent drain current with the gate voltages and controlling the output power with the input power. rohs compliance ? ra45h8994m1 is a rohs compliant product. ? rohs compliance is indicate by the letter ?g? after the lot marking. ? this product include the lead in the glass of electronic parts and the lead in electronic ceramic parts. how ever, it is applicable to the follo wing exceptions of rohs directions. 1.lead in the glass of a cathode-ray tube, electronic parts, and fluorescent tubes. 2.lead in electronic ceramic parts. ordering information: order number supply form RA45H8994M1-101 antistatic tray, 10 modules/tray 4 1 5 23 1 rf input added gate voltage 1(p in &v gg1 ) 2 gate voltage 2(v gg2 ), power control 3 drain voltage (v dd ), battery 4 rf output (p out ) 5 rf ground (case) block diagram package code: h2m
