The utility model discloses a
test fixture for a
radio frequency power
amplifier board of a
base station, which belongs to the field of fixture testing and specifically comprises a heat dissipation bottom plate, a heat dissipation fan, a to-be-tested product placement platform, a power supply module, a filter and a fixture
assembly. The to-be-tested product placing platform, the
power module and the clamp
assembly are arranged above the heat dissipation bottom plate, the heat dissipation fan is arranged on one side of the to-be-tested product and the
power module, the filter is arranged on one side, away from the
power module, of the to-be-tested product placing platform, and the clamp
assembly comprises a test plate, a supporting column fixing frame and a clamp control mechanism. The clamp control mechanism is fixedly connected with the test plate and is in sliding connection with the support column fixing frame, the lower surface of the test plate is a test surface, and the upper surface is provided with cooling fins; according to the invention, the production requirements of high-efficiency power
amplifier testing can be met, product positioning can be rapidly and accurately carried out, cable connection is reduced, the heat dissipation capability and the shielding capability are excellent, and the device is suitable for
rapid testing or long-time aging testing of products.
