data sheet adg904/adg904 - r rev. c | page 11 of 16 applications the adg904 and adg904 - r are ideal solutions for low power, high frequency application s. the low inser tion loss, high isolation between ports, low distortion, and low current consumption of these parts make them excellent solutions for many high frequency switching applications. they may be used in applications such as switchable filters, t ransmitters and receivers for radar systems , and communication s systems from base stations to cell phones. the adg9xx wideband switches are designed to meet the demands of devices that transmit at ism band frequencies of 1 ghz and higher . the low insertion loss, high isolation between ports, single pin control interface, no requirement for dc blocking capacitors , and ttl interface compatibility of these parts make them cost - effective and an easy - to - integrate switching solution for many high frequency switch ing applications and low power applications where the parts can handle up to 16 dbm of power . absorptive vs. refle ctive the adg904 is an absorptive (matched) switch with 50 ? terminated shunt legs ; the adg904 - r is a reflective switch with 0 ? terminated s hunts to ground. the adg904 absorptive switch has a good vswr on each port, regardless of the switch mode. an absorptive switch should be used when there is a need for a good vswr that is looking into the port but not passing the through signal to the comm on port. the adg904 is therefore ideal for applications that require minimum reflections back to the rf source. it also ensures that the maximum power is transferred to the load. the adg904 - r reflective switch is suitable for applications where high off po rt vswr does not matter , and the switch has other performance feature s . it may be used in many applica - tions, including high speed filter selection. in most cases, an absorptive switch may be used instead of a reflective switch, but not vice versa. antenna diversity switch the adg904 is ideal for use as an antenna diversity switch, switching different antenna s in to the tuner. the low insertion loss ensur es minimum signal loss and high isolation between channels , making these sp4t switches suitable for switc hing applications in tuner modules and set - top boxes. tuner adg904 cable rf1 rf2 rf3 rf4 vga antenna 04504-0-021 figure 27 . tuner modules filter selection the adg904 can be used to switch high frequency signals between different filters and to multiplex the signal to the output. these s p4t switches are also ideal for high speed signal routing. rf out rfc adg904 adg904 rf1 rf2 rf3 rf4 rf1 rf2 rf3 rf4 rf in rfc 04504-0-022 figure 28 . filter selection t x /r x switching the low insertion loss and high isolation between ports ensure that the adg904 and adg904 - r are suitable transmit/receive swi tch es f or all ism band and w ireless lan , providing the required isolation between the transmit signal and the receive signal . adg904 tx rx rx rx rx antenna 04504-0-023 figure 29 . tx/rx switching
