can you tell me what category this meets in En 300 200 ? 1 2 or 3?
I mean category 1 2 or 3 for receiver spec on the En 300 220


Category 1,2 or 3 in Rx only refers to blocking spec. The ADF7021 is class 2 in
terms of blocking. There is an additional requirement for a Category 1 receiver
– Adjacent Channel Rejection (ACR). The ADF7021 cannot achieve this.

The ADF7021-V can achieve category 1 performance in terms of blocking and ACR
for channel spacing of 25kHz. At 12.5kHz channels, the part fails the ACR
