| MICROWAVE CORPORATION v01.0701 HMC230MS8 4 dB LSB GaAs MMIC 3-BIT DIGITAL ATTENUATOR, 0.75 - 2.0 GHz Features 4 dB LSB Steps to 28 dB Single Positive Control Per Bit +/- 0.5 dB Typical Bit Error Pin - For - Pin Replacement to AA100-59 Digital Attenuator Typical Applications The HMC230MS8 is ideal for: 9 ATTENUATORS - SMT * Cellular * PCS, ISM, MMDS * WLL Handset * Base Station Infrastructure Functional Diagram General Description The HMC230MS8 is a broadband 3 - bit positive control GaAs IC digital attenuator in an 8 lead MSOP surface mount plastic package. Covering 0.75 to 2 GHz, the insertion loss is typically less than 2 dB. The attenuator bit values are 4 (LSB), 8, and 16 dB for a total attenuation of 28 dB. Accuracy is excellent at 0.5 dB typical with an IIP3 of up to +48 dBm. Three bit control voltage inputs, toggled between 0 and +3 to +5 volts, are used to select each attenuation state at less than 50 uA each. A single Vdd bias of +3 to +5 volts applied through an external 5K Ohm resistor is required. Electrical Specifications, TA = +25 C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated) Parameter Insertion Loss Attenuation Range Return Loss (RF1 & RF2, All Atten.

Application Circuit DC blocking capacitors C1 & C2 are required on RF1 & RF2. Choose C1 = C2 = 100 ~ 300 pF to allow lowest customer specific frequency to pass with minimal loss. R1 = 5K Ohm is required to supply voltage to the circuit through either PIN 1 or PIN 5. 9 - 10 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com MICROWAVE CORPORATION v01.0701 HMC230MS8 4 dB LSB GaAs IC 3-BIT DIGITAL ATTENUATOR, 0.75 - 2.0 GHz Absolute Maximum Ratings Control Voltage (V1, V2, V3) Bias Voltage (Vdd) Storage Temperature Operating Temperature RF Input Power (0.75 - 2 GHz) Vdd to +0.5 Vdc +8.0 Vdc -65 to +150 C -40 to +85 C +26 dBm 9 ATTENUATORS - SMT NOTES: 1.

These Resistors are optional and may be used to enhance decoupling of the RF path from the control inputs. The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads should be connected directly to the ground plane similar to that shown. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board as shown is available from Hittite Microwave Corporation upon request.
