Switchable Multi-Channel Amplifiers
Phase and Amplitude Matched
Spectrum Control offers state-of-the-art Multi-Channel Amplifiers used in demanding military frequency calibration systems. These 2, 3, and 4 channel modules are all phase matched, amplitude matched and offer both single and multiple path logic.
These units allow the engineer to either distribute an amplified signal to multiple ports, or measure the amplified output from up to 4 auxiliary ports.

Phase Matched
- The Model BXMF1020 as shown on the left is a 4 channel design which features phase and amplitude matching on all 4 channels, including 4 auxiliary ports used to measure the amplified output signal. Machined Channeled paths help to provide up to 60 dB Channel to Channel Isolation with PIN Diode switches used for high speed, high isolation performance.
Amplitude Matched
- The design features a low pass clean up filter for improved spectral purity, and the entire chassis is laser welding providing superior hermeticity and environmental protection.
Built in input over-drive protection
- The model BXMF1019 on the left is a two channel design which allows for rapid 200 ns switching from either a common distributed port to a dual input-output phase matched configuration. Each mode is configured using TTL logic and gain for either path is identical. All channels are phase matched to one another, amplitude matched and offer exceptional out of band rejection, isolation and spurious free dynamic range performance.
Wide-bandwidth: 2 to 8 GHz
- With each path, the model BXMF1020 adds an additional 16 dB of gain with output power of +10 dBm from 500 MHz to 2000 MHz. This model is easily configurable to alter the gain, power and frequency bandwidth depending upon the customer’s unique requirements.
