2-way active splitter in BOX

2-way active splitter in BOX

This is very useful device - this is active splitter version in enclosure. It can provide equal voltages, equal current, or equal power to matched or unmatched loads. Input low noise amplifier can eliminate insertion loss of the splitter and add small gain.

Using

Antenna splitter
RX signal divider

Main functions

Broadband: 0.1 MHz to 60 MHz
2-way splitter
Passive (4.5 dB loss) or Active (up to 14 dB gain)
Bypass of Preamp by relays
Low loss, high gain, low noise, high IP3 preamplifier
Front-end protections - high voltage / current
50 / 75 Ohm impedance - easy jumper switch
Electrostatic protection by neon lamps
High power protection
Quality SMA connectors
Aluminium enclosure: W x H x L = 74 x 29 x 100
4pcs self adhesive feet pads included
DC plug included
ASSEMBLED and TESTED VERSION

Parameters

Impedance 50 or 75 Ohm
NPN transistor 2SC5551A
Supply voltage 12 - 14 V
BIAS current 10 to 70 mA
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 +17 dBm
Bypass of Preamp without supply voltage
Insertion loss with preamp OFF: around 1.5 dB together with the splitter around 4.5 dB
