The HMC305SLP4E is a broadband 5-bit positive control Silicon IC digital attenuator with CMOS compatible serial-to-parallel driver package in a leadless QFN 4x4 mm SMT package. Covering 0.4 to 6 GHz, the insertion loss is typically less than 1.6 dB. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.25 dB typical with an IIP3 of up to +52 dBm. Five bit serial control words are used to select each attenuation state. A single Vcc bias of +3.3V to +5V is required.The HMC305S(E) is a replacement for the HMC305A(E), HMC305B(E) and HMC305(E).ApplicationsCellular InfrastructureWireless InfrastructureMicrowave Radio & VSATTest Instrumentation

The HMC306AMS10 & HMC306AMS10E are general purpose broadband 5-bit positive control GaAs IC digital attenuators in 10 lead MSOP surface mount plastic packages. Covering 0.7 to 3.8 GHz, the insertion loss is typically less than 1.5 to 2.3 dB. These attenuators’ bit values are 0.5 (LSB), 1, 2, 4 and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ± 0.2 dB typical with an IIP3 of up to +52 dBm. Five bit control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state. A single Vdd bias of +3 to +5V applied through an external 5K Ohm resistor is required.APPLICATIONSCellular; UMTS/3G InfrastructureISM, MMDS, WLAN, WiMAXMicrowave Radio & VSATTest Equipment and Sensors

The HMC311LP3(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT DC to 6 GHz amplifiers. This 3 × 3mm QFN packaged amplifier can be used as either a cascadable 50 Ω gain stage or to drive the LO of HMC mixers with up to +17 dBm output power. The HMC311LP3(E) offers 14.5 dB of gain and an output IP3 of +32 dBm while requiring only 56 mA from a +5V supply. The Darlington feedback pair used results in reduced sensitivity to normal process variations and yields excellent gain stability over temperature while requiring a minimal number of external bias components.ApplicationsCellular / PCS / 3GFixed Wireless & WLANCATV & Cable ModemMicrowave Radio

The HMC316MS8(E) is a miniature double balanced mixer in 8 lead plastic surface mount package. The passive GaAs schottky diode mixer implements planar on chip balun transformers, and requires no external components. The mixer can be used as an upconverter, downconverter, or modulator. At mid-band the mixer provides 7.5 dB conversion loss and +25 dBm IIP3 with LO drive levels of +19 dBm. The design was optimized for low cost high volume applications where high converter linearity is required.ApplicationsCellular BasestationsCable ModemsFixed Wireless Access SystemsWiMAX
