With Tx bypassed, this bi-directional amplifier features the lowest noise figure LNA and high-speed switching circuit between Tx and Rx.

Designed for Helium and all radios with strong output power that require receive gain but don’t need any amplification on the Tx side. The Tx path on this unit is bypassed with minimum signal loss. The Rx side gets a full 15dB of gain, improving the receive sensitivity by many folds. All this while keeping the noise figure at a minimum.

The receive side is fitted with a 902~928MHz or 863~870 MHz bandpass filter.

An extremely highly efficient unit that consumes only 45mA of current at 6V DC.

 Offered in 902~928MHz and 863~870MHz bands (optional). Utilizes ultra-low noise LNA on the receive side with 16dB of gain. Tx gain set at 6dB for use with Helium and other mining devices. 0dB or bypass option available as well.

Salient Features:

1. Transmit Gain: 6dB Tx gain is sufficient to recover all cable/connector losses and give full 1watt power that’s legally allowed in most areas.
2. LNA: The built-in Ultra Low Noise Amplifier with a signal gain of 16 dB improves the receive sensitivity of remote equipment while keeping the noise level very low.
3. Receive Filtering: The bandpass filter on this amplifier gives added protection against out-of-band noise.
4. Enclosure: The unit is housed in patented housing that does not require mounting hardware and seals to a completely watertight unit with a twist of a hand. A state-of-the-art unit.
5. Power consumption: With only 5 watt of power consumption during max transmit and 0.25W during Rx, this product is the most efficient product available anywhere.
6. DC Injector: With only 0.8dB insertion loss, this DC injector is the lowest loss available anywhere. Enclosed in a specially designed machined aluminum housing.
7. Warranty: All Shireen’s amplifier products come with a 2-year warranty and are made in the USA.

This linear high power, bi-directional amplifier is designed for 902~928 MHz radio products. Works equally well with all types of radios (Specially OFDM). Designed in a completely weatherproof housing for all outdoor applications. The unit is powered over coax with DC injector.

The latest version of 900MHz OEM amplifier module gives peak power of 2watt with 12dB of Tx gain.

The light weight, small size and flexible power supply options of this amplifier make it ideal for portable 900MHz ISM band operation in applications such as model aircraft, telemetry, robotics, industrial controls etc.. The fast receive/transmit switching time make this amplifier an ideal range boosting option for widely available radios that employ Time Division Duplexing technologies (FHSS, DSSS, OFDM etc.)

A highly efficient amplifier that consumes only 45mA of power during Rx mode. It can be powered via regulated 5V DC or unregulated 6~14V DC.
