3-way active splitter in BOX

Using

• Antenna splitter into more receivers
• 10 MHz reference signal splitter
• Antenna splitter into more SDR/skimmers

Main functions

• Broadband: 0.1 MHz to 60 MHz
• could be used up to 150 MHz
• 3-way RX splitter
• Passive (< 6 dB loss) or Active (up to 13 dB gain)
• Very low difference between output ports, less than 0.1 dB @ 50 MHz
• Bypass of the Preamp by relays
• Low insertion loss, high gain, low noise, high IP3 preamplifier
• Input diode limiter
• 50/75 Ohm impedance - easy jumper switch

Parameters

• Impedance 50 or 75 Ohm
• Insertion loss with preamp OFF: around 6 dB
• Insertion loss with preamp ON: compensated by preamp, up to gain around 12 dB (in to out)
• Very low difference between output ports, less than 0.1 dB @ 50 MHz
• Isolation > 17 dB port 1-2 and 2-3, > 23 dB port 1-3
• SWR on OUTPUT ports better than 1 : 1.1 on HF, resp. 1 : 1.19 on 6m
• SWR on IN port around 1 : 1.2 to 1 : 1.7 depends on gain of preamp (Gain 10 dB = SWR 1 : 1.2)
• Preamp transistor 2SC5551A
• Supply voltage 12 - 14 V (13.8 V recommended)
• BIAS current 10 to 70 mA (preset to 40 mA @ 13.8 V)
• Supply current up to 180 mA includes relays!
• Gain: up to 14 dB
• Low Noise Figure (NF) 1.2 dB (20 mA 50 MHz)
• Low Noise Figure (NF) < 2 dB (60 mA 50 MHz)
• REAL IP3 34 dBm
• Input diode limiter about +24 dBm
• Bypass of the Preamp without supply voltage
