MRF5S4125NR1
MRF5S4125NBR1
Designed for broadband commercial and industrial applications with
frequencies up to 500 MHz. The high gain and broadband performance of
these devices make them ideal for large-signal, common-source amplifier
applications in 28 volt base station equipment.
• Typical Single-Carrier N-CDMA Performance @ 465 MHz: VDD = 28 Volts,
450-480 MHz, 25 W AVG., 28 V
SINGLE N-CDMA
I
DQ = 1100 mA, Pout = 25 Watts Avg., IS-95 CDMA (Pilot, Sync, Paging,
Traffic Codes 8 Through 13). Channel Bandwidth = 1.2288 MHz. PAR =
9.8 dB @ 0.01% Probability on CCDF.
Power Gain — 23 dB
Drain Efficiency — 30.2%
ACPR @ 750 kHz Offset — -47.6 dBc in 30 kHz Bandwidth
