The F1130 RF front-end offers a 19dB 获得 with 3.5dB NF and +37dBm OIP3 performance. The digital 步 attenuator provides a 30dB adjustment 范围 in 2dB 步s via the SPI interface controller. For strong signal conditions, each RF amplifier can be bypass-controlled via the SPI interface. The RF front-end output and mixer input signals are bonded to separate pins to allow interstage image-reject filtering.
Each of the dual mixer paths provides a 9dB power 获得, 10.3dB NF, and +36dBm OIP3 performance. An external LO signal is applied to the mixer LO port. This device is 包裹d in a 7mm × 7mm 48-VFQFPN with 50? single-ended RF and LO inputs, and 200? differential IF 输出阻抗 for ease of integration.
The F1130EVB is a fully populated evaluation board that allows the customer to easily evaluate the F1130 Dual Path RF to IF Mixer.
