WiNRADiO WR
|
This device contains an ultra-low noise figure preamplifier designed to
operate in the range of 30-3500 MHz. While it is ideally matched to
WiNRADiO VHF/UHF receivers, it can be also used to improve sensitivity
of most third party receivers.
The amplifier employs the latest Silicon Germanium
Heterostructure Bipolar Transistor technology (SiGE HBT) to
achieve its excellent performance, in terms of high gain, low noise
figure and excellent third-order intercept.
The device is housed in a sturdy die-cast package which can be
mounted indoors as well as outdoors, and powered either locally or via
the coaxial cable. It is suited for consumer as well as professional
applications. |
The WiNRADiO WR-LNA-3500 Low Noise Amplifier is especially
suitable for use with WiNRADiO G3 series VHF/UHF receivers, such as the WR-G305i and WR-G305e
receivers, in conjunction with which it can provide excellent minimum
discernible signal (MDS) levels of approximately -140 dBm. The amplifier
also contains a suitable high-pass filter to eliminate interference from AM
broadcast and HF frequencies.
Installation
|
The amplifier is connected to the antenna and the receiver via an SMA
connector and a suitable low-loss coaxial cable. In this type of
installation the power is applied directly to the down-converter. We
recommend using well-filtered power, preferably that of a linear power
supply, such as the WiNRADiO
SF-41 series (which is already supplied with the
amplifier).
|
|
Alternatively, the amplifier can be placed closer to the antenna and
powered via the coaxial cable. On the receiver side, the power can be
injected via WiNRADiO
WR-BT-3500 "Bias T" device. This would be a preferred
option to minimize losses in the cable if the antenna is located at a
greater distance from the receiver.
