Products

WASP

Description

The WASP set of products includes a block DownConverter board, block UpConverter board, and an optional low-noise amplifier (LNA) PreSelector.

DownConverter

WASP Block DownConverter board downconverts a 2 GHz wide frequency block in any portion of the 6 GHz to 26.5-GHz frequency range to a 500 MHz to 2500 MHz L-band intermediate frequency (IF). The low phase noise local-oscillator (LO) synthesizer has available LO output. Onboard reference conditioning is available for 10-MHz external reference with 10-MHz and 100-MHz reference outputs. The onboard power distribution accepts any input voltage between +8 VDC and +34 VDC, and the onboard microcontroller unit (MCU) provides external USB, serial peripheral interface (SPI), and I2C communication interfaces for communication and control.

UpConverter

WASP Block UpConverter board upconverts a 500-MHz to 2500-MHz frequency block to any portion of the 6-GHz to 26.5-GHz frequency range. The low phase noise local-oscillator (LO) synthesizer has available LO output. Onboard reference conditioning is available for 10-MHz external reference with 10-MHz and 100-MHz reference outputs. Optional output buffer delivers up to +10 dBm to drive power amplifiers. Onboard power distribution accepts any input voltage between +8 VDC and +34 VDC, and the onboard microcontroller unit (MCU) provides external USB, SPI, and I2C communication interfaces for communication and control.

PreSelector

WASP LNA PreSelector is a low-noise amplifier with a switched filter bank. Covering the 6-GHz to 26.5-GHz range, the low-noise amplifier and switched filter bank can be inserted ahead of the WASP Block DownConverter input to improve image rejection and NF. The board is controlled by the MCU on the downconverter board through an I2C interface connection. The preselector board can also be used with the WASP Block Upconverter board output to reduce harmonics and spurious frequencies.
