HMC197A / 197AE v02.1210 GaAs MMIC SOT26 SPDT SwITCh, DC - 3 Ghz Features Low insertion Loss: 0.4 dB Ultra Small Package: SOt26 input iP3: +45 dBm Positive control: 0/+3V @ 3 µA Typical Applications the hMc197A(e) is ideal for: • MMDS & wirelessLAN • PcMciA wireless cards • Portable wireless Functional Diagram General Description the hMc197A(e) is a low-cost SPDt switch in a 6-lead SOt26 plastic package for use in general switching applications which require very low insertion loss and very small size. the device can control signals from Dc to 3 Ghz and is especially suited for 900 Mhz, 1.8 - 2.2 Ghz, and 2.4 Ghz iSM applications with less than 1 dB loss. the design provides exceptional insertion loss performance, ideal for filter and receiver switching. RF1 and RF2 are reflective shorts when “Off”. the two control voltages require a minimal amount of Dc current and offer compatibility with most cMOS & ttL logic families. See hMc221A(e) for same performance in an alternate SOt26 pin-out. 14 SwitcheS - SPDt - SMt Electrical Specifications, TA = +25° C, Vctl = 0/+3 to +8 Vdc, 50 Ohm System Parameter Frequency Dc - 1.0 Ghz Dc - 2.0 Ghz Dc - 2.5 Ghz Dc - 3.0 Ghz Dc - 1.0 Ghz Dc - 2.0 Ghz Dc - 2.5 Ghz Dc - 3.0 Ghz Dc - 1.0 Ghz Dc - 2.0 Ghz Dc - 2.5 Ghz Dc - 3.0 Ghz 0.5 - 1.0 Ghz 0.5 - 3.0 Ghz 0.5 - 1.0 Ghz 0.5 - 3.0 Ghz Dc - 3.0 Ghz tRiSe, tFALL (10/90% RF) tON, tOFF (50% ctL to 10/90% RF) 3 10 ns ns 24 24 18 14 20 16 14 10 25 23 40 38 Min. typ. 0.4 0.45 0.7 0.8 28 28 22 18 30 22 17 13 30 29 45 43 Max. 0.7 0.8 0.9 1.1 Units dB dB dB dB dB dB dB dB dB dB dB dB dBm dBm dBm dBm insertion Loss isolation Return Loss input Power for 1dB compression (Vctl = 0/+5V) input third Order intercept (Vctl = 0/+5V) (two-tone input Power = +7 dBm each tone) Switching characteristics 14 - 1 For price, delivery and to place orders: Hittite Microwave Corporation, 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or apps@hittite.com HMC197A / 197AE v02.1210 GaAs MMIC SOT26 SPDT SwITCh, DC - 3 Ghz Isolation 0 Insertion Loss 0 -0.5 INSERTION LOSS (dB) -10 -1 ISOLATION (dB) -20 -1.5 -30 -2 -2.5 -40 -3 0 0.5 1 1.5 2 2.5 3 -50 0 0.5 1 1.5 2 2.5 3 FREQUENCY (GHz) FREQUENCY (GHz) Return Loss 0 Input 0.1 and 1.0 dB Compression vs. Control Voltage 35 1 dB at 1900 MHz 14 SwitcheS - SPDt - SMt 14 - 2 P1dB & P0.1dB (dBm) -10 RETURN LOSS (dB) 30 1 dB at 900 MHz -20 25 0.1 dB at 900 MHz -30 20 -40 0.1 dB at 1900 MHz -50 0 0.5 1 1.5 2 2.5 3 15 3 4 5 6 7 8 9 FREQUENCY (GHz) CONTROL INPUT (V) Input Third Order Intercept Point vs. Control Voltage 54 Distortion vs. Control Voltage control input (Vdc) +3 +5 +8 third Order intercept (dBm) +7 dBm each tone 900 Mhz 50 50 51 1900 Mhz 49 49 50 52 IP3 (dBm) 50 48 Truth Table 900 MHz 1900 MHz *Control Input Voltage Tolerances are ± 0.2 Vdc. control input* A (Vdc) 8 9 46 control current ia (µA) -3 3 -5 5 -32 32 ib (µA) 3 -3 5 -5 32 -32 Signal Path State RF to RF1 ON OFF ON OFF ON OFF RF to RF2 OFF ON OFF ON OFF ON B (Vdc) +3 0 +5 0 +8 0 44 2 3 4 5 6 7 0 +3 0 +5 0 +8 CONTROL INPUT (V) For price, delivery and to place orders: Hittite Microwave Corporation, 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or apps@hittite.com HMC197A / 197AE v02.1210 GaAs MMIC SOT26 SPDT SwITCh, DC - 3 Ghz Absolute Maximum Ratings control Voltage Range (A & B) Storage temperature Operating temperature eSD Sensitivity (hBM) -0.2 to +12 Vdc -65 to +150 °c -40 to +85 °c class 1A input Power for 1.0 dB compression (dBm) 24 30 33 Compression vs. Control Voltage carrier at 900 Mhz control input (Vdc) +3 +5 +8 input Power for 0.1 dB compression (dBm) 21 28 32 input Power for 1.0 dB compression (dBm) 24 30 34 carrier at 1900 Mhz input Power for 0.1 dB compression (dBm) 21 27 31 eLectROStAtic SeNSitiVe DeVice OBSeRVe hANDLiNG PRecAUtiONS caution: Do not operate in 1dB compression at power levels above +31 dBm (Vctl = +5 Vdc) and do not “hot switch” power levels greater than +20 dBm (Vctl = +5Vdc).

Set logic gate and switch Vdd = +3V to +5V and use hct series logic to provide a ttL driver interface. 2. control inputs A/B can be driven directly with cMOS logic (hc) with Vdd of 5 to 8 Volts applied to the cMOS logic gates. 3. Dc Blocking capacitors are required for each RF port as shown. capacitor value determines lowest frequency of operation. 4. highest RF signal power capability is achieved with Vdd = +8V and A/B set to 0/+8V.
