Please see pictures and data table. **Every individual item is tested prior to shipment** Common types of duplexers: Duplexers typically come in two types, bandpass / bandpass, and lowpass / highpass. Other types are less common. In cellular applications uplink / downlink duplexers are typically bandpass / bandpass, due to high isolation required between transmit and receive. In LTE C/A downlink carrier aggregation, lowpass / highpass are common as the aggregated spectrum typically (not always) is sufficiently far apart in frequency. In dual band WiFi where 2.4GHz and 5GHz signals share antennas, high pass and low pass duplexers are common since 2.4 GHz and 5 GHz are far apart in frequency, although the 2.4 GHz and 5 GHz paths will have their individual bandpass filters as well, in addition to the lowpass/highpass WiFi duplexer. Common uses of duplexers in the field and in the lab: Case 1: Duplexing The RF system has separate paths at different frequencies (e.g. TX vs RX) and must share common antenna. Duplexer is used to enabled both paths share a common port. Case 2: Un-duplexing The RF system is already duplexed on to a common antenna port. For example your DUT is a commercial cellphone. You need to test receive without being compressed by the transmit on the same RF path. The RF paths can be simply separated by a duplexer. Case 2a: specific cellular test case By inserting a pair of duplexers between the UE / handset and LTE basestation, the RX and TX can be completely separated for test. This allows tweaking the propagation channel for DL / UL or both, receiver testing without interference from TX, or transmitter EVM measurements.
